[idea] Function keys as indexed keybinds

[OlivierPelletier]

idea / problem

I would like to be able to use my F keys for tab switching.

requested change

Possibility to support keybinds like this:

[keys]
switch_tab = "f1..f12"

or alternatively like this:

[keys]
switch_tab_1 = "f1"
switch_tab_2 = "f2"
switch_tab_3 = "f3"
switch_tab_4 = "f4"
...

why you want this

I've always found F keys on smaller keyboard to be an ergonomic way of switching tab. I've been using F keys to switch tab with tmux and zellij. I think it would be a good addition to herdr.
