Currently, [https://en.wikipedia.org/wiki/Wayland_%28display_server_protocol%29 Wayland] uses [https://www.x.org/wiki/XKB/ XKB] for keyboards, but they are not modifiable during runtime using e.g. <code lang=console>setxkbmap</code> by default. The keyboard layout must be configured and then the session restarted. | |||

Modifying the Linux keyboard to support APL keys via [https://linux.die.net/man/1/xmodmap xmodmap(1)] is possible, but not recommended — it has been superseded by the [https://wiki.archlinux.org/title/X_keyboard_extension X keyboard extension] (XKB). Generally <source lang=console inline>xmodmap</source> is best for simple tasks,<ref>ArchWiki Contributors. [https://wiki.archlinux.org/title/xmodmap xmodmap]. 19 July 2021</ref> which APL keyboards often tend not to be. [[Dyalog APL]], for example, has native support for XKB.<ref name="Dyalog APL XKB"/> | |||

=== Gnome catches keystrokes before Dyalog === | |||
After upgrading Ubuntu 21.04 (Hirsute Hippo), Gnome catches the keystrokes from the <kbd>Super</kbd> key to show the list of applications, before Dyalog can receive it. [[#setxkbmap|Changing the shifting key]] from <source lang=console inline>grp:win_switch</source> to <source lang=console inline>grp:caps_switch</source> avoids the issue. Changing it to <source lang=console inline>grp:rctrl_switch</source> does not work. | |||
