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+/”.
