I'm interested in hijacking the Fn key on my laptop and using it as the mod key for tmux, but after a bunch of tinkering with xmodmap and tmux.config, I'm not much further along in getting this to work.
- xev shows that they key name is XF86WakeUp, but this doesn't work as a key in tmux.config.
- I've tried setting the hex code for XF86WakeUP (0xF8) in tmux, but this doesn't work either.
- I know that the Fn key sending its own code is something of a fluke, but it's a fluke I'd like to take advantage of now and worry about the consequences later (it's a valuable key in a valuable space!)
