I configured mutt to use vim as an editor to write emails (with
set editor=vim in
.muttrc), and I have noticed that when I am in tmux (with an empty
.tmux.conf), the vim keybinding CTRL-K in insert mode, which is handy to insert digraphs, does not work.
Outside of Tmux && mutt, everything works fine: typing CTRL-K causes the character
? to temporarily appear under the cursor, and the next two characters I type are correctly interpreted as a digraph.
Does anyone know where the error might be coming from?
