bind $mod+d to nop?

[trharmon0]

$mod+d is normally mapped to a shortcut which starts regolith-control-center. I run that tool very infrequently and it happens to collide with the default i3 keybind for i3's run tooling when access a remote i3 session over, say, SPICE or x2go. So I'd like to demap/mask that keybinding for my own use. I'd like to avoid taking on the maintenance responsibility of overriding any partials or modifying the defaults files on the system and outside of my user's home dir. So I've been trying this:

bindsym $mod+d nop

from my i3 99_conf in ~/.config/regolith3... However, on config reload this causes i3 to complain about a duplicate keybinding for nop.

I've been digging around to find where a keybinding to nop might be hiding but the defaults from the packages are a bit, well, it's hard to grok where to look. I find the i3 partials / default but they are variablized with $wm... and I'm not finding where those resource names are being set.

Anyone have any advice on how to map that bind to nop so I can re-use it or to change the default keybind for regolith-control-center via my Xresources so as to avoid a collision with remote i3 (non-regolith) sessions?

thx

Hi @trharmon0!

I'm not finding where those resource names are being set.

You can find all of the official XResource files in /usr/share/regolith. Here's what mine looks like, although I'm running sway instead of i3 it doesn't really matter.

Anyone have any advice on how to map that bind to nop so I can re-use it or to change the default keybind for regolith-control-center via my Xresources so as to avoid a collision with remote i3 (non-regolith) sessions?

First let's find the existing mapping for <mod> d. We can grep for "set_from_resource" as settings for bindings, and look for d:

$ find /usr/share/regolith | xargs grep -HsF 'set_from_resource' | grep ' d'
...
/usr/share/regolith/sway/config.d/60_config_keybindings:set_from_resource $wm.binding.display wm.binding.display d
...

There is a convention in Regolith XResource files that the programs launched by keybindings are also defined in Regolith. For any .binding. key, there is a .program. key that specifies the program to launch.

$ find /usr/share/regolith | xargs grep -HsF "wm.program.display"
/usr/share/regolith/sway/config.d/60_config_keybindings:set_from_resource $wm.program.display wm.program.display regolith-control-center display
/usr/share/regolith/sway/config.d/60_config_keybindings:bindsym $mod+$wm.binding.display exec --no-startup-id $wm.program.display

We can simply redefine the wm.program.display value to a "nop". I think : would be better than nop because the latter is a valid program name. You would do this with:

echo "wm.program.display: :" >> ~/.config/regolith3/Xresources

After refresh or relogin the d keybinding should be a no-op! I tested this and worked for me. LMK if you still see the original behavior.

1. Yes! That worked! Ty!

2. I was pulling the 'nop' thing from the i3 manual. It's interesting that it collides with another CLI program from graphviz.

3. Setting the Xresource to ':'. Is that some sort of Xresources trick? I haven't found it in the man page.

3: It's at a lower level. I was searching through bash stuff but this was the truthiest thing I could find (quickly): https://www.mankier.com/1p/colon
