Obviously the normal ones are: Ctrl-x
, Ctrl-u
Alt
can be a good leader prefix. Alt-x
is emacs-extended-command
. Alt-m
is used by spacemacs.
Visual Studio has Ctrl-k
, Ctrl-e
, but IMO, they are not good. Those are very "hot" keys that are used all the time
Tmux has Ctrl-b
, which is almost always rebound to Ctrl-a
for memory compatibility with Screen's Ctrl-a
. It's also not good IMO, but Tmux is used very often that it is reasonable to include Ctrl-a
as a leader key.
One I've started playing with is Ctrl-Insert
- it has almost no conflicts. There are also Ctrl-Numlock
and Ctrl-Scrolllock
