Push-to-Talk Keys

Everything related to the official iOS Mumble client
Help! I can't seem to set my PTT input to something like a simple keystroke such as "\" or "`". Is there a reason for this? The game I play while using Mumble (WoW) uses most of the other keystrokes so I have to use the keys that are not bound to game functions. What inputs can I use for PTT?
Are you on OS X? If so, try enabling "Advanced" in Preferences. Then visit Shortcuts.

It'll explain the issue.

If you are on Yosemite or Mavericks, you'll need to do something along these lines instead of what's described in the app:

(Basically, enable Mumble in the Privacy/Accessibility screen in System Preferences.)

Hopt it helps.
