How to send a key to the pane?

[niya3]

Works from terminal:
tmux send-key -t 0 Enter
->

user@host$
user@host$

Doesn't work in libtmux:

>>> import libtmux
>>> pane = libtmux.Server().get_by_id('$1').attached_pane
>>> pane
Pane(%5 Window(@4 2:a, Session($1 foo)))
>>> pane.send_keys('Enter')

->

user@host$  Enter
Enter: command not found

up. oh, #13 -_-

What keys are you trying to send?

pane.send_keys('')

send_keys automatically sends enter, unless you do enter=False:

pane.send_keys('echo "Hi"', enter=False)

I'm trying to send Enter, Up, Down, and other special keys.

man tmux

tmux allows a command to be bound to most keys, with or without a prefix
key. When specifying keys, most represent themselves (for example ‘A’ to
‘Z’). Ctrl keys may be prefixed with ‘C-’ or ‘^’, and Alt (meta) with
‘M-’. In addition, the following special key names are accepted: Up,
Down, Left, Right, BSpace, BTab, DC (Delete), End, Enter, Escape, F1 to
F20, Home, IC (Insert), NPage/PageDown/PgDn, PPage/PageUp/PgUp, Space,
and Tab.

Does pane.send_keys('') work to send Enter?

Also, you can try the other keys as well, does send_keys('Left', enter=False, suppress_history=False) work?
