Since windows are more akin to tabs in Emacs, and I am way more used
|
||||
to it than Tmux, all keybinds are prefixed with a =Tab=, itself prefixed
|
||||
with the main prefix.

In order to access more easily the different windows, I want to be able to type =<prefix> TAB <window number>=. However, I’m using the bépo layout, numbers are available only when pressing shift. Otherwise, the characters typed are ="«»()@+-/*= (from 1 to 0).
