For me it was sending commands to named panes. Let me automate some pretty annoying apps that demanded to be run in an open console.

    Did you end up using send-keys for that?

    I've dealt with that kind of thing in the past, and one thing I wanted to do that I never found a good solution for was to make it so that a pane was "read only" in that it could be scrolled with a mouse, but accept key presses (with page up/down arrows doing scrolling as a stretch goal). Did you ever deal with that/find a solution?

    I've never tried scrolling with mouse but it does work with arrow keys and pgupdn.

    Yes to send-keys.

    Scrolling with a mouse works, just not exactly the way I thought it would when I started using it.

    I started out with a shell script using send-keys, and eventually decided the python tmux library was a nice improvement.

    Nice. I wrap send-keys with a little perl script, I should look into that Python lib.

    It's not bad at all. It gets monumentally easier if you've named all your sessions and windows because it's just a .get() to look them up. Panes still have that thing where the panes can get renumbered inside a window, but still have the same internal immutable identifier underneath the hood, but you wind up with pane.send_keys(my_string, enter=True) which is well worth the learning curve IMO.
