Something I have been looking for very long. Finally I was instructed.
In my i3wm config, I have the following keychain section,
bindsym $mod+n mode "focused"
mode "focused"
{
[...snip...]
# Exit to the default mode
bindsym Return mode "default"
bindsym Escape mode "default"
}
In there, add the line bindsym q exec i3-input -F '[workspace=%s] kill' -P 'Kill workspace: ', mode "default"
The intended behaviour: Mod+n triggers the “focused” mode, wherein “q” key triggers the dialogue to name the workspace where all windows would be killed.
Nice stuff, i3wm developers, and simple enough so that I should have figured it out on my own.
