Alt key binding not great from Mac. :(

[NHDaly]

Hi! Lovingggggg TPM. It just makes sense.

That said, after uninstalling plugins moved from prefix C to prefix alt u, I had trouble pressing it on the mac. I did eventually find the setting on iTerm2 to move option to +Esc, and this allows me to hit this key binding, but I'd rather not do that.

I use option for special characters in a lot of what I type (a lot of what I type isn't always in english, and option enables things like ¨ ´ ``` etc.)

Can there be a setting to change the binding, or can we settle on something more universal? thanks!

--- Edit ---
I see this was referenced in #31. Just starting an issue for the discussion! :)

Any suggestions? It's hard to find keys that do not conflict with other (OS/terminal/readline) bindings..

Is <prefix>-C (for Clean) available? That's what I've bound it to on my local machine.

<prefix>-R would be another option, for "Remove".

Why

The 'Terminal' app re-map the alt key function

Solutions

1. If you are using iTem2 you can change the default options here:
   
   Just modify the alt key's behavior to +Esc

2. If you don't wan't to change the terminal options you can modify the @tpm-clean value in your tmux.conf to re-map the default clean key binding

etc:

set -g @tpm-clean 'u'

any idea how to change option key to meta key in Alacritty?

@guoliang just add this to tmux.conf and reload:

set -g @tpm-clean 'u'

Now you can uninstall by press <prefix>+u (e.g.: control+b+u)
