I'm on a mac, so some of the function keys shortcuts don't work without a bunch of messing around, which I'd rather avoid. Instead, I'd really like to just execute the command the keyboard shortcut would have executed, but I can't figure out how to do that.
Specifically, I want to create a new session, and the keybindings file says: C-S-F2 new-session. How do I run new-session from inside an existing byobu session?
