Many people use <code>caps:ctrl_modifier</code> and <code>caps:escape</code> in <code>xkb_options</code> (see <a href="https://man.openbsd.org/xkeyboard-config">xkeyboard-config(7)</a> for other options) to make Caps Lock function as an extra Ctrl or Esc key. - </p> - <p> - If all you want to do is do a relatively common modification like that, chances are that <code>xkb_variant</code> and <code>xkb_options</code> already has what you want, and you should just set that. - </p> - <hr /> - <p> - But if what you want isn't covered in the standard XKB files, hear my story. I personally wanted Caps Lock to function as an additional Shift key, which isn't covered in <code>xkb_options</code>. (<code>caps:shift</code> doesn't differ much from normal Caps Lock, make it confusingly documented and doesn't make the Caps Lock function as an extra Shift.) - </p> - <p> - On X11, I would simply use <code>xmodmap -e "keysym Caps_Lock = Shift_L"</code>. Now my Caps Lock functions as an extra Left Shift. Works just alright. - </p> - <p> - But now that I switched to Wayland, Sway in particular, <code>xmodmap</code> for X11 isn't going to work. What I ended up doing was the following: - </p> - <p> - <b><code>$HOME/.xkb/symbols/gbcustom</code></b> - </p> -<pre>default partial alphanumeric_keys -xkb_symbols "basic" { // leave "basic" in-tact unless you know what you're doing - include "gb" // or whatever base layout you use, most likely "us" - name[Group1] = "English (UK) Customized"; - key <CAPS> { [ Shift_L, Shift_L, Shift_L, Shift_L ] }; -};</pre> - <p> - Note that here, the "<code>key</code>" lines are in the form <code>key <X> { [ A, B, C, D ] } ;</code>, where "<code>X</code>" is the keycode symbolic name of the physical key you want to press. In my case, it is <code>CAPS</code>. Check <code>/usr/share/X11/xkb/symbols/pc</code> and <code>/usr/share/X11/xkb/symbols/latin</code>, or the relevant files for your keyboard configuration, to look up the keycode symbolic name from the name you're used to. (Looking up <code>Shift_L</code> in <code>symbols/pc</code> gets you to <code>LFSH</code>, which is what you would use in place of "<code>X</code>". <code>A</code> is triggered when <code>X</code> is pressed alone, <code>B</code> when it's pressd with Shift, <code>C</code> with AltGr, and <code>D</code> with both AltGr and Shift. - </p> - <p> - <b><code>$HOME/.config/sway/config</code></b> - </p> -<pre>input "1:1:AT_Translated_Set_2_keyboard" { - xkb_layout "gbcustom" -}</pre> - <p> - Of course, replace "<code>1:1:AT_Translated_Set_2_keyboard</code>" with your actual keyboard identifier listed in <code>swaymsg -t get_inputs</code>. And reload Sway. - </p> - <p> - There might be better ways to do so, but I've got this to work. For these unusual setups, it is a bit complicated and not as straightforward as adding a <code>xmondmap</code> line to <code>.xinitrc</code>. Hopefully things would get better as Wayland matures. - </p> - <p> - <a href="https://github.com/swaywm/sway/issues/4250">This GitHub issue</a> and <a href="https://www.city17.xyz/keychron/#xkb-here-be-dragons">jman's article on this</a> were extremely helpful.
