hotkey to toggle microphone mute (ALT + F4) shows a speaker, not a microphone

[James Hunt]

This is incorrect for 2 reasons:

1) The overlay should show a microphone icon since that is what is being toggled.
2) It's currently using the same icon as the speaker / sound output mute hotkey (ALT + F1).
