Comment 6 for bug 1759462

Additional Info:

I just found out another detail quite by accident.

My system is set up to use the “fn” key to make the F buttons behave as an f button (F1-12). Meaning by default a press will trigger the volume up/down, etc.

So when the audio keys conk out… my other f key functions (brightness, etc) still work. BUT, if I hold “alt”, and press my audio keys - they work!

Now knowing this pattern, - I went through my F keys… and tested what worked (brightness, audio, mute, search)

    F1 (mute) - “F1” works with the “fn” key, and the mute only works when also pressing “alt”
    F2 (vol down) - “F2” works with the “fn” key, and the vol down only works when also pressing “alt”
    F3 (vol up) - “F3” works with the “fn” key, and the vol up only works when also pressing “alt”
    F4 (disable mic) - Works as expected.
    F5 (bright down) - Works as expected.
    F6 (bright up) - Works as expected.
    F7 (projector) - Untested.
    F8 (airplane mode) - Works as expected.
    F9 (tools) - Does not work in any capacity
    F10 (Search) - “F10” works with the “fn” key, and the search only works when also pressing “alt”
    F11 (launchA) - Works as expected.
    F12 (open file browser) - Works as expected.
