* (nicm) Rewrite command handling so commands are much more generic and the
same commands are used for command line and keys (although most will probably
need to check how they are called). Currently incomplete (only new/detach/ls
implemented).
* (nicm) String number arguments. So you can do: tmux bind ^Q create "blah". * (nicm) String number arguments. So you can do: tmux bind ^Q create "blah".
* (nicm) Key binding. tmux bind key command [argument] and tmux unbind key. * (nicm) Key binding. tmux bind key command [argument] and tmux unbind key.
Key names are in a table in key-string.c, plus A is A, ^A is ctrl-A. Key names are in a table in key-string.c, plus A is A, ^A is ctrl-A.
