Finch control file named as
~/.gntrc
Here's a small example taken from finch FAQ to show how to rebind alt+ctrl+n to switch to the next window: In ~/.gntrc, add
[GntWM::binding] c-a-n = window-next
Note that, the default binding alt+n will continue to switch to the next window. If you want to unbind that, add
[GntWM::binding] a-c-n = window-next a-n=
To see the list of available rebindable actions for the focused widget, press “alt+/”.
