Of course you're right. I myself use Mod4 as ModKey, which is why I
didn't encounter any conflicts (and why I used that keybinding in the
first place).
But I forgot all about this when I copied my changes to a clean config
for the patch.

As for the function's declaration and definition, I simply followed
the customfuncs (
https://dwm.suckless.org/customisation/customfuncs/
) page.
I didn't know about the usage of tabs, but I'll use them then.
Thanks!
