HowTo: Add or change i3 Keybindings

1. Consult the i3 User's Guide to find out which feature you'd like to add or change.
2. Stage your own i3 config file, then open ~/.config/regolith/i3/config in your editor of choice.
3. The lines which start with bindsym map keys to actions. $mod means the modifier key, which by default is ⊞ Win. For example bindsym $mod+Return exec /usr/bin/st will cause i3 to run /usr/bin/st when ⊞ Win and Return are pressed at the same time.
4. Update an existing line or add a new one based on your needs. For example, to cause i3 to use tabbed layout mode, when ⊞ Win and t are pressed, add this to the config file: bindsym $mod+t workspace_layout tabbed
5. After making the change, save the file and reload i3 with ⊞ Win + Shift + r.
