I was using byobu on Ubuntu 11.10 Server and I needed to hit a function key in an app, so I hit F9 to bring up the config menu and switched the keybinding set from "f-keys" to "screen-escape-keys". That worked, but now I can't re-enable all the f-keys.
I found a program
byobu-config that brings up the menu again, and I can switch back to screen keys from there. This fixes things for new screen processes, but the effect on the current screen session is weird: it disables the Ctrl+a (screen) keys and restores F2-F8, but F9-F12 still don't do anything (they're just passed on to the foreground process).
What's up with this? Any ideas? Thanks in advance.
