+[[blindness-intro]]
+== Introduction
+
+This chapter describes assistive technologies for users who are blind, focusing primarily on screen readers and tools designed to work in conjunction with them.
+The chapter deliberately contains no images and aims to minimize the use of elements other than plain text.
+
+[[screen-reader]]
+== Screen Reader
+
+Currently, screen readers function only within the extref:{handbook}x11[X Window System] and are not supported in the crossref:virtual-terminal[virtual-terminal,Virtual Terminal].
+FreeBSD does not currently support Braille displays, so they rely exclusively on speech synthesizers.
+
+[[orca]]
+=== Orca
+
+Orca is a widely used and well-known open source screen reader.
+It offers a comprehensive set of features and is available on FreeBSD through the package:accessibility/orca[] package.
+
+[[orca-install]]
+==== Installation
+
+To install it, execute:
+
+[source,shell]
+....
+# pkg install orca
+....
+
+[[orca-launch]]
+==== Launch
+
+Orca can be launched in several ways.
+From a terminal, type:
+
+[source,shell]
+....
+% orca
+....
+
+Some desktop environments provide a keyboard shortcut to launch Orca:
+
+- XFCE: `Super` + `Alt` + `s`
+- GNOME `Super` + `Alt` + `S`
+
+[TIP]
+====
+The Super key is usually labeled as Windows icon, Command icon, or "Super".
+Refer to https://en.wikipedia.org/wiki/Super_key_(keyboard_button) for more information.
+====
+
+[[orca-usage]]
+==== Usage
+
+Orca provides a manual page: man:orca[1].
+However, most of the documentation is available online.
+The main reference is the starting point in the https://gnome.pages.gitlab.gnome.org/orca/help/[Orca Users Guide], which includes:
+
+ - Getting Started
+ - Reading Documents and Web Pages
+ - Reviewing and Interacting with Screen Contents
+
+The screen reader includes many keyboard commands for navigation and interaction.
+Refer to the https://gnome.pages.gitlab.gnome.org/orca/help/commands.html[Orca's Commands] page for a full list.
+
+[[orca-config]]
+==== Configuration
+
+Orca can be configured through a graphical settings interface. To open it, run:
+
+[source,shell]
+....
+% orca -s
+....
+
+Configuration options are documented on the https://gnome.pages.gitlab.gnome.org/orca/help/preferences.html[Orca's Preferences Dialogs] page.
+
+[[yasr]]
+=== yasr
+
+The package:accessibility/yasr[] utility is a lightweight screen reader that operates exclusively in a terminal environment.
+Yasr requires a speech synthesizer to work.
+Its default configuration file is set up to use package:accessibility/eflite[].
+
+To install both yasr and eflite, run:
+
+[source,shell]
+....
+# pkg install yasr eflite
+....
+
+To start the screen reader, execute:
+
+[source,shell]
+....
+% yasr
+....
+
+The global configuration file for yasr is located at [.filename]#/usr/local/share/yasr/yasr.conf#.
+To create a user-specific configuration file, copy the global one to your home directory:
+
+[source,shell]
+....
+% cp /usr/local/share/yasr/yasr.conf ~/.yasr.conf
+....
+
+For details on configuration options and keyboard shortcuts, refer to man:yasr[1].
+
+[[blindness-ports]]
+== Ports Collection
+
+FreeBSD provides the extref:{handbook}ports[Ports Collection], which offers a simple way to install applications.
+Some ports allow you to configure options before building and installation.
+By default, configuration is handled through a TUI menu not accessible by a screen reader.
+
+The package:ports-mgmt/portoptscli[] utility is a text-only tool specifically designed to configure ports using a screen reader.
+To install it, run:
+
+[source,shell]
+....
+# pkg install portoptscli
+....
+
+Then add to [.filename]#/etc/make.conf#:
+
+[.programlisting]
+....
+DIALOG4PORTS=/usr/local/bin/portoptscli
+....
+
+From now on, the Ports framework will automatically invoke portoptscli whenever a port offers configurable options.
+
+For detailed information about its features and usage, refer to the manual page man:portoptscli[1] and consult the online https://gitlab.com/alfix/portoptscli/-/raw/main/README.txt[README].
+
+[[blindness-editor]]
+== Editor
+
+[[ed]]
+=== ed
+
+The man:ed[1] utility is a line-oriented text editor used to create, view, and modify text files.
+It is included by default in a standard FreeBSD installation.
+To start the editor, run:
+
+[source,shell]
+....
+% ed
+....
+
+ed is a powerful editor.
+Refer to its manual page man:ed[1] for a complete overview of its features and command syntax.
+
+[WARNING]
+====
+ed does not support multibyte characters and may not handle non-ASCII text correctly.
+Alternatively, consider using crossref:blindness[edbrowse,edbrowse], which offers robust text editing features in addition to its browsing capabilities.
+====
+
+[[blindness-internet-web]]
+== Internet and WEB
+
+[[edbrowse]]
+=== Edbrowse
+
+Edbrowse is a text-based browser, editor, IRC chat client, and mail client, specifically designed for screen reader users.
+Its interface is similar to man:ed[1], but with extended functionality.
+
+[[edbrowse-install]]
+==== Installation
+
+To install package:www/edbrowse[], execute:
+
+[source,shell]
+....
+# pkg install edbrowse
+....
+
+[[edbrowse-usage]]
+==== Usage
+
+To launch Edbrowse, run:
+
+[source,shell]
+....
+% edbrowse
+....
+
+The first time you run edbrowse, it will not find the configuration file [.filename]#~/.ebrc#.
+It will automatically create a default configuration file, display a message, and exit:
+
+[source,shell]
+....
+% edbrowse
+Your edbrowse config file is missing; a default file has been created for you.
+Before running edbrowse again, take the time to personalize your config file:
+/home/yournickname/.ebrc
+edbrowse -c to edit
+%
+....
+
+You can now relaunch Edbrowse; it will use the default configuration file.
+To customize it, either run:
+
+[source,shell]
+....
+% edbrowse -c
+....
+
+Or use your preferred text editor, for example:
+
+[source,shell]
+....
+% ed ~/.ebrc
+....
+
+[TIP]
+====
+Example configuration files are provided in [.filename]#/usr/local/share/doc/edbrowse/#.
+These include:
+
+ - sample.ebrc: with comments in English
+ - sample_fr.ebrc: with comments in French
+ - sample_it.ebrc: with comments in Italian
+====
+
+[[edbrowse-doc]]
+==== Documentation
+
+The utility provides a manual page: man:edbrowse[1].
+However, the main documentation is available online in the https://edbrowse.org/usersguide.html[User's Guide].
+
+The package also installs a local copy of the documentation at [.filename]#/usr/local/share/doc/edbrowse/usersguide.html#.
+To view it using edbrowse, run:
+
+[source,shell]
+....
+% edbrowse /usr/local/share/doc/edbrowse/usersguide.html
+....
+
+Translated versions of the user guide are available in the same directory:
+
+ - usersguide_es.html: Spanish
+ - usersguide_fr.html: French
+ - usersguide_pt_br.html: Brazilian Portuguese
+
+[[blindness-liblouis]]
+== Liblouis
+
+package:devel/liblouis[] is a translator for many languages to and from Braille.
+It provides a large number of conversion tables.
+To install, execute:
+
+[source,shell]
+....
+# pkg install liblouis
+....
+
+The package installs both libraries and utilities.
+The translation utility is man:lou_translate[1].
+
+The following example demonstrates how to transcribe the text `FreeBSD Accessibility Handbook` into Braille with English Grade 2 translation table and the unicode.dis display table.
+The final output is Braille encoded as Unicode dot patterns.
+
+[source,shell]
+....
+% echo "FreeBSD Accessibility Handbook" | lou_translate -f unicode.dis,en-us-g2.ctb
+⠠⠋⠗⠑⠑⠠⠠⠃⠎⠙⠀⠠⠁⠒⠑⠎⠎⠊⠃⠊⠇⠰⠽⠀⠠⠓⠯⠃⠕⠕⠅
+....
+
+Documentation and additional examples for this utility are available on the project website, specifically in the https://liblouis.io/documentation/liblouis.html#Testing-Translation-Tables-interactively[Testing Translation Tables interactively] section of the official documentation.

+[[colors-intro]]
+== Introduction
+
+This chapter explains how to configure colors for on-screen elements, including:
+
+- Setting high-contrast color schemes in graphical environments.
+- Adapting screen color temperature for optimal viewing in daylight and nighttime conditions.
+- Selecting colors for configuration ports menus.
+
+[[high-contrast-theme]]
+== High Contrast Theme
+
+Graphical Environments allow you to easily install and set up graphical themes.
+This paragraph describes how to configure high contrast themes for windows.
+
+[[xfce-high-contrast]]
+=== XFCE
+
+Download from https://www.xfce-look.org/p/2289345[High Contrast Windows 11 Themes]:
+
+- _Adwaita-Dusk.tar.bz2_
+- _Adwaita-Desert.tar.bz2_
+- _Adwaita-Aquatic.tar.bz2_
+- _Adwaita-NightSky.tar.bz2_
+
+The example is for _NightSky_, but of course you can choose whichever theme you prefer.
+
+[source,shell]
+....
+% tar xzvf Adwaita-NightSky.tar.bz2 <1>
+% mkdir ~/.themes <2>
+% cp -a Adwaita-NightSky ~/.themes/ <3>
+% rm Adwaita-NightSky.tar.bz2 <4>
+% xfconf-query -c xfwm4 -p /general/theme -s 'Adwaita-NightSky' <5>
+% xfconf-query -c xsettings -p /Net/ThemeName -s 'Adwaita-NightSky' <6>
+....
+
+<.> Extract the downloaded theme archive.
+<.> Create the [.filename]#~/.themes# directory if it does not already exist.
+<.> Copy the extracted themes into [.filename]#~/.themes#.
+<.> Optionally, delete the original compressed file to save space.
+<.> Apply the Adwaita-NightSky theme for the XFCE desktop environment.
+<.> Apply the Adwaita-NightSky theme for GTK applications.
+
+The theme selection steps (5 and 6) can also be performed using the graphical configuration dialogs in XFCE:
+
+[source,shell]
+....
+% xfwm4-settings
+% xfce4-appearance-settings
+....
+
+[[high-contrast-icon]]
+== High Contrast Icons
+
+Graphical Environments allow you to easily install and set up icon themes.
+This paragraph describes how to configure high contrast icons.
+
+[[xfce-icon-high-contrast]]
+=== XFCE
+
+Run the following commands to use the _Treepata - High Contrast_ icons theme with XFCE.
+
+Download _Treepata.zip_ from https://www.xfce-look.org/p/1015854[Treepata - High contrast].
+Then execute:
+
+[source,shell]
+....
+# pkg search zip <1>
+% unzip Treepata.zip <2>
+% mkdir ~/.icons <3>
+% cp -a Treepata ~/.icons/ <4>
+% rm Treepata.zip <5>
+% xfconf-query -c xsettings -p /Net/IconThemeName -s Treepata <6>
+....
+
+<.> Install the package package:archivers/zip[]:
+<.> Extract the downloaded archive file.
+<.> Create the [.filename]#~/.icons# directory if it does not already exist.
+<.> Copy the extracted theme into [.filename]#~/.icons#.
+<.> Optionally, delete the downloaded archive file to free up space.
+<.> Set the _Treepata_ icon theme.
+
+The icon theme (step 6 above) can also be set graphically via the `_Appearance_` dialog under the `_Icons_` tab.
+To do so, open the dialog and select your preferred icon theme:
+
+[source,shell]
+....
+% xfce4-appearance-settings
+....
+
+[NOTE]
+====
+If you have icon theme problems, install package:misc/hicolor-icon-theme[] and package:graphics/gtk-update-icon-cache[]:
+
+[source,shell]
+....
+# pkg install hicolor-icon-theme gtk-update-icon-cache
+....
+
+Run man:gtk-update-icon-cache[1] to create or update the icon cache:
+
+[source,shell]
+....
+% gtk-update-icon-cache -f -t ~/.icons/treepata
+....
+
+====
+
+[[colors-temperature]]
+== Color temperature
+
+This paragraph explains various utilities that adjust screen colors based on temperature, day/night cycles, and gamma settings.
+These utilities enable both interactive color adjustments and automatic changes based on the local time and geographical location.
+Some utilities are compatible with the extref:{handbook}x11[X Window System], others support extref:{handbook}wayland[Wayland], and some work on both display servers.
+
+.Color Temperature Utilities

+| package:accessibility/wlsunset[]
+
+|===
+
+The rest of this section details the steps to install, configure, and launch the utilities.
+
+[[colors-darkman]]
+=== darkman
+
+man:darkman[1] is a daemon that automatically manages transitions between dark mode and light mode.
+It operates primarily in the background, switching the screen's color scheme based on the local time of the current location.
+To install, run:
+
+[source,shell]
+....
+# pkg install darkman
+....
+
+Create the file [.filename]#~/.config/darkman/config.yaml# and write your latitude and longitude.
+Example:
+
+[.programlisting]
+....
+lat: 37.52
+lng: 122.16
+....
+
+The utility does not directly change the screen colors; instead, it calls external utilities to perform the color transitions.
+Add scripts to be executed at sundown by placing them in [.filename]#$XDG_DATA_DIRS/dark-mode.d/#
+and scripts to be executed at sunrise by placing them in [.filename]#XDG_DATA_DIRS/light-mode.d/#.
+Several https://gitlab.com/WhyNotHugo/darkman/-/tree/main/examples[example scripts] are available in the project repository.
+
+To start darkman manually, run:
+
+[source,shell]
+....
+% darkman run &
+....
+
+The utility also offers some interactive options; for more details refer to the man:darkman[1] manual page.
+
+[[gammastep]]
+=== gammastep
+
+The man:gammastep[1] utility adjusts your screen’s color temperature automatically based on your location.
+To install, run:
+
+[source,shell]
+....
+# pkg install gammastep
+....
+
+The utility works out of the box without any configuration.
+Simply start it by running:
+
+[source,shell]
+....
+% gammastep &
+....
+
+[NOTE]
+====
+If you encounter any issues, customize the configuration by adapting the link:https://gitlab.com/chinstrap/gammastep/-/blob/master/gammastep.conf.sample[gammastep.conf.sample] file and save it as [.filename]#~/.config/gammastep/conf.ini#.
+Refer to the link:https://gitlab.com/chinstrap/gammastep/-/blob/master/README.md[README] for troubleshooting.
+====
+
+[[redshift]]
+=== redshift
+
+The man:redshift[1] utility find your position and sets the color temperature accordingly.
+To install, execute:
+
+[source,shell]
+....
+# pkg install redshift
+....
+
+The redshift utility runs without any configuration.
+To start it, simply execute:
+
+[source,shell]
+....
+% redshift &
+....
+
+The utility might hang while trying to determine the location or the correct method to set the color.
+In this case, specify them explicitly using `-l _latitude:longitude_` and `-m _method_`.
+The available methods can be listed by running: `% redshift -m list`.
+
+Example of running redshift with an explicit location and method:
+
+[source,shell]
+....
+% redshift -l 37.86:-122.27 -m randr &
+....
+
+To make this setting permanent, add the following lines to [.filename]#~/.config/redshift/redshift.conf# file:
+
+[.programlisting]
+....
+[redshift]
+adjustment-method=randr
+location-provider=manual
+
+[manual]
+lat=37.86
+lon=-122.27
+....
+
+[NOTE]
+====
+The project provides a default https://github.com/jonls/redshift/blob/master/redshift.conf.sample[redshift.conf.sample] configuration file.
+For troubleshooting and additional information, please refer to the https://github.com/jonls/redshift/blob/master/README.md[README].
+====
+
+[[sct]]
+=== sct
+
+The man:sct[1] utility is a simple command-line tool for controlling screen color temperature.
+It does not update automatically and must be run repeatedly to adjust the temperature over time.
+To install, execute:
+
+[source,shell]
+....
+# pkg install sct

+
+[[colors-ports]]
+== Ports Collection
+
+FreeBSD provides the extref:{handbook}ports[Ports Collection], which offers a simple way to install applications.
+Some ports allow you to configure options before building and installation.
+By default, configuration is handled through a TUI menu built by the package:ports-mgmt/portconfig[].
+The colors can be customized in several ways:
+
+. Terminal color capabilities.
+. The $NO_COLOR environment variable.
+. The $PORTCONFIG_THEMEFILE environment variable.
+. The global [.filename]#/usr/local/etc/portconfig/theme.conf# file.
+
+[NOTE]
+====
+These methods are listed in order of decreasing priority and are mutually exclusive, meaning only one can be active at a time.
+====
+
+*1. Terminal Colors*
+
+man:portconfig[1] automatically detects whether the terminal supports colors.
+If not, it defaults to a black-and-white theme.
+
+*2. NO_COLOR*
+
+If the `$NO_COLOR` environment variable is set and not empty, portconfig forces the black-and-white theme
+
+.Example persistent setting `$NO_COLOR`
+[example]
+====
+[.filename]#/etc/make.conf#
+
+[.programlisting]
+....
+export NO_COLOR=YES
+....
+====
+
+*3. PORTCONFIG_THEMEFILE*
+
+If the `$PORTCONFIG_THEMEFILE` environment variable is set and points to a valid theme file, it will be used.
+Otherwise, the default theme is applied.
+
+..Example persistent setting `$PORTCONFIG_THEMEFILE`
+[example]
+====
+[.filename]#/etc/make.conf#
+
+[.programlisting]
+....
+export PORTCONFIG_THEMEFILE=/home/foo/mytheme.conf
+....
+====
+
+[TIP]
+====
+To create a new theme file, run:
+
+[source,shell]
+....
+% /usr/local/bin/bsddialog --save-theme mytheme.conf --infobox "Saving theme..." 0 0
+....
+====
+
+*4. Global theme.conf*
+
+If the file [.filename]#/usr/local/etc/portconfig/theme.conf# exists and is valid, it will be used.
+If not, the default theme is applied.
+
+[TIP]
+====
+Sample themes are included in [.filename]#/usr/local/etc/portconfig/#:
+
+- blackwhite.conf
+- default.conf
+- red-green.conf
+- yellow-blue.conf
+
+To use the yellow-blue.conf theme:
+[source,shell]
+....
+# ln -s /usr/local/etc/portconfig/yellow-blue.conf /usr/local/etc/portconfig/theme.conf
+....

+== Introduction
+
+This chapter provides resources for developers seeking to make their programs accessible, test accessibility, and improve the accessibility of their software.
+
+[[devel-colors]]
+== Colors
+
+Do not assume that users can distinguish all (or even any of) the colors used in your program.
+While official statistics on the prevalence of color blindness are lacking, it is estimated that approximately 5% of the population is affected by some form of it, whether partial or total.
+
+[[devel-color-guidelines]]
+=== Colors Guidelines
+
+Avoid using color as the sole means of conveying information.
+If color must be used, provide a straightforward and well-documented method for configuring color settings.
+Where possible, ensure support for the `$NO_COLOR` environment variable to accommodate user preferences.
+
+[[devel-color-checkers]]
+=== Colors Checker
+
+The package:graphics/kontrast[] package provides the Kontrast GUI utility to check if the color combinations are distinct enough to be readable and accessible.

+[[lowvisin-intro]]
+== Introduction
+
+This chapter outlines accessibility features available in graphical desktop environments designed for users with low vision, such as virtual magnifiers, easy-to-read fonts, and screen scaling.
+
+[[hidpi]]
+== Desktop Size
+
+Graphical environments allow users to adjust the desktop display size, a feature commonly known as screen scaling or HiDPI scaling.
+The goal is to enlarge desktop elements such as icons, text, and windows to improve visibility and accessibility.
+
+[[xfce-hidpi]]
+=== XFCE
+
+To set a custom scaling factor, for example 4, run the following command:
+
+[source,shell]
+....
+% xfconf-query -c xsettings -p /Gdk/WindowScalingFactor -s 4
+....
+
+Alternatively, HiDPI scaling can be enabled with a fixed 2x factor using the graphical interface.
+This option is available in the `_Appearance_` dialog, under the `_Settings_` tab as `_Window Scaling_`.
+To open the `_Appearance_` dialog, execute:
+
+[source,shell]
+....
+% xfce4-appearance-settings
+....
+
+[[lowvision-font]]
+== Font
+
+The package:x11-fonts/atkinson-hyperlegible[] provides the _atkinson-hyperlegible_ font.
+It is designed for good readability, the letter shapes aim to increase character recognition.
+To install, execute:
+
+[source,shell]
+....
+# pkg install atkinson-hyperlegible
+....
+
+The remainder of this section describes how to set up fonts in various graphical environments using _atkinson-hyperlegible_ as an example.
+
+[[xfce-fonts]]
+=== XFCE
+
+XFCE allows you to select the font and size for window titles and content text, as well as the font size for icon labels.
+
+[source,shell]
+....
+% xfconf-query -c xfwm4 -p /general/title_font -s "Atkinson Hyperlegible 15" <1>
+% xfconf-query -c xsettings -p /Gtk/FontName -s "Atkinson Hyperlegible 15" <2>
+% xfconf-query -c xsettings -p /Gtk/MonospaceFontName -s "Atkinson Hyperlegible 15" <3>
+% xfconf-query -c xfce4-desktop -p /desktop-icons/use-custom-font-size -s true <4>
+% xfconf-query -c xfce4-desktop -p /desktop-icons/font-size -s 15.0 <5>
+....
+
+<.> Set the window title font to _Atkinson Hyperlegible_, size 15.
+<.> Set the window content font to _Atkinson Hyperlegible_, size 15.
+<.> Set the monospace font within windows to _Atkinson Hyperlegible_, size 15.
+<.> Enable custom font sizing for icons.
+<.> Set the icon font size to 15.0.
+
+Alternatively, you can configure the same settings using the graphical XFCE configuration dialogs.
+
+To select the font for window titles, open the `_Window Manager_` dialog:
+
+[source,shell]
+....
+% xfwm4-settings
+....
+
+To choose the font used inside windows, open the `_Appearance_` dialog and go to the `_Fonts_` tab:
+
+[source,shell]
+....
+% xfce4-appearance-settings
+....
+
+[TIP]
+====
+In the Fonts tab, you can also adjust options such as `_anti-aliasing_`, `_Hinting_`, `_Sub-pixel order_`, and `_Custom DPI_`.
+For more details, see the https://docs.xfce.org/xfce/xfce4-settings/appearance#fonts[XFCE documentation].
+====
+
+To set the font size for icons, open the `_Desktop_` dialog and go to the `_Desktop Icons_` tab where you can adjust the icon font size:
+
+[source,shell]
+....
+% xfdesktop-settings
+....
+
+[[magnify]]
+== Magnify
+
+This section describes various utilities that magnify portions of the screen, acting as virtual magnifying lenses.
+Some tools continuously enlarge the area beneath the mouse cursor, while others do not.
+Certain utilities automatically move the magnified window to follow the cursor, whereas others keep it fixed in place.
+

+% mag
+....
+
+[NOTE]
+====
+xmag does not display a magnified area immediately upon launch.
+Click anywhere on the screen with the left mouse button to select a region, and xmag will open a window showing a magnified view of that area.
+The application window includes a few buttons offering limited functionality.
+====
+
+[[xzoom]]
+=== xzoom
+
+The man:xzoom[1] utility is a screen magnifier for the X Window System that updates the magnified view in real time.

+
+[[lowvision-mouse]]
+== Mouse
+
+[[mouse-apparance]]
+=== Apparance
+
+Some desktop environments allow you to change the size, color, and other graphical properties of the mouse cursor.
+
+[[xfce-mouse]]
+==== XFCE
+
+XFCE allows you to set the size and color of the mouse pointer via `_Mouse and Touchpad_` dialog.
+To run the dialog start:
+
+[source,shell]
+....
+% xfce4-mouse-settings
+....
+
+Then click on the `_Theme_` tab to select a size and a style.
+
+[NOTE]
+====
+Some themes, included the _Default_, do not support cursor size customization.
+====
+
+Alternatively, you can achieve the same result via the `xfconf-query` command.
+The following example set the current theme cursur to size 50:
+
+[source,shell]
+....
+% xfconf-query -c xsettings -n -p /Gtk/CursorThemeSize -s 50
+....
+
+[[find-mouse-cursor]]
+=== Find Cursor
+
+Some desktop environments provide a visul feedback of the mouse pointer's current position.

+Xfce draws large red circles around the mouse pointer.
+Type:
+
+[source,shell]
+....
+% xfce4-find-cursor
+....
+
+The above command draws circles for a few seconds.
+
+**Keyboard Shortcut**
+
+XFCE allows to add a keyboard shortcut.
+Circles are drawn for as long as the shortcut keys are pressed.
+To use the shortcut before enable the feature then choose the key combination to bind to `xfce4-find-cursor`.
+
+Example to enable and bind `Ctrl` + `Super` + `k`:
+[source,shell]

+[[vt4-intro]]
+== Introduction
+
+Virtual Terminal, commonly referenced and documented as man:vt[4] is the system's built-in extref:{handbook}ports[virtual console].
+It is installed by default, provides a command-line interface, and starts automatically at boot.
+This chapter presents an overview and examples of key features and utilities relevant to visual accessibility.
+
+[[vt4-colors]]
+== Colors
+
+The Virtual Terminal supports color configuration both via configuration files and interactively through a dedicated utility.
+
+[[vt4-colors-loader]]
+=== Loader.conf
+
+Colors can be set and saved using the man:loader.conf[5] file.
+To change a default color, add a line in the following format:
+`kern.vt.color._colornum_.rgb="_colorspec_"`, where:
+
+ - `_colornum_` is the numeric identifier of the color to be customized (see the table below).
+ - `_colorspec_` is a specification of the color, either as a comma-separated RGB triplet (red, green, and blue, each value from 0 to 255) or as an HTML-style hexadecimal value.
+
+.Default palette: Color, color number, default color in rgb, default color in html.
+[options="header", cols="1,1,1,1"]
+|===
+| Color | _colornum_ | default _colorspec_ RGB | default _colorspec_  html

+
+|===
+
+[[vt4-example-loader-conf-colors]]
+.Set background in white, text in black, boot messages in red.
+[example]
+====
+[.filename]#/boot/loader.conf#
+
+[.programlisting]
+....
+# Background black to white
+kern.vt.color.0.rgb="255,255,255"
+
+# Text light gray to black
+kern.vt.color.7.rgb="0,0,0"
+
+# Boot white to red
+kern.vt.color.15.rgb="255,0,0"
+
+....
+====
+
+[[vidcontrol]]
+=== Vidcontrol
+
+The man:vidcontrol[1] utility allows you to configure colors interactively.
+Use the `show` option to display the list of available colors:
+
+[source,shell]
+....
+% vidcontrol show
+....
+
+To set the foreground color, use `vidcontrol _color_`.
+For example, to set the text color to green:
+
+[source,shell]
+....
+% vidcontrol green
+....
+
+To set both foreground and background colors, use `vidcontrol _foreground_ _background_`.
+For example, to set blue text on a green background:
+
+[source,shell]
+....
+% vidcontrol blue green
+....
+
+Configurations made with man:vidcontrol are not persistent across shutdown.
+To make the settings permanent, add the following line to man:rc.conf[5]:
+`allscreens_flags="-c _foreground_ _background_"`.
+
+[[vt4-vidcontrol-colors-rc]]
+.Set blue foreground and green background.
+[example]
+====
+[.filename]#/etc/rc.conf#
+
+[.programlisting]
+....
+allscreens_flags="-c blue green"
+
+....
+====
+
+[NOTE]
+====
+Setting allscreens_flags="-c _colors_" in [.filename]#/etc/rc.conf# takes effect after the system boots.
+To change the colors during the boot process, edit [.filename]#/boot/loader.conf# as crossref:virtual-terminal[vt4-colors-loader,previously described].
+====
+
+[[vt4-resolution]]
+== Resolution
+
+The `kern.vt.fb.default_mode="<width>x<height>"` option in man:loader.conf[5] allows you to configure the display resolution.
+Technically, it specifies the display mode of the Virtual Terminal, allowing you to control the size of elements displayed on the screen.
+
+[[vt4-example-resolution]]
+.Sets the width to 800 and the height to 600.
+[example]
+====
+[.filename]#/boot/loader.conf#
+
+[.programlisting]
+....
+kern.vt.fb.default_mode="800x600"
+
+....
+====
+
+[[vt4-font]]
+== Font
+
+Virtual Terminal allows you to configure the font in use, and the system supports installing and utilizing additional fonts.
+
+[[vt4-select-font]]
+=== Select a Font
+
+The utilities man:vidfont[1] and man:vidcontrol[1] can load a font from [.filename]#/usr/share/vt/fonts/#.
+To list the currently available fonts:
+
+[source,shell]
+....
+% ls /usr/share/vt/fonts
+....
+
+Usually a file name has the format `<name>-<width>x<height>`, where:
+
+ - `<name>` is the font name.
+ - `<width>x<height>` is the size.
+
+man:vidfont[1] provides an interactive menu in a Text User Interface to select a font.
+Run the following command:
+
+[source,shell]
+....
+% vidfont
+....
+
+Alternatively, man:vidcontrol[1] provides a CLI, `vidcontrol -f _font_`.
+Example for `spleen-32x64.fnt`:
+
+[source,shell]
+....
+% vidcontrol -f spleen-32x64.fnt
+....
+
+[TIP]
+====
+Tip: You can omit the _.fnt_ extension when specifying the file name.
+For example, to load `spleen-32x64.fnt`, use:
+
+[source,shell]
+....
+% vidcontrol -f spleen-32x64
+....
+====
+
+Settings configured with either utility are not preserved after a reboot.
+
+[[vt4-vidcontrol-font-rc]]
+.Select the font to load at each startup.
+[example]
+====
+[.filename]#/etc/rc.conf#
+
+[.programlisting]
+....
+allscreens_flags="-f spleen-32x64.fnt"
+
+....
+====
+
+[[vt4-new-font]]
+=== New Fonts
+
+The man:vtfontcvt[8] utility allows you to convert a font into the .fnt format for use in the Virtual Terminal.
+The converted font must be copied to [.filename]#/usr/share/vt/fonts/# and selected as crossref:virtual-terminal[vt4-select-font,previously described].
+
+[[vt4-bell]]
+== Bell
+
+The terminal bell can be activated by:
+
+[source,shell]
+....
+# sysctl kern.vt.enable_bell=1
+....
+
+To make the configuration persistent after reboot, save it in either man:loader.conf[5] or man:sysctl.conf[5].
+
+[[vt4-example-bell]]
+.Active the bell at each startup.
+[example]
+====
+[.filename]#/boot/loader.conf#
+or
+[.filename]#/etc/sysctl.conf#
+
+[.programlisting]
+....
+kern.vt.enable_bell=1
+
+....
+====
