Minor - UI - (H)ot keys

[anjenpai]

Bug:
    when trying to assign a hot key to zoom on an area, trying to select any hot key will immediately 
    return the selection to the first one in the list
Expected behavior:
    pressing the desired hot key should select it
Replicate:
    (H)ot keys -> (F2) / (F3) .... (Shift + F8)
Workaround:
    go to the screen you want to zoom to, enter the (H)ot keys menu, ( \ )disable multiplex, assign 
    your desired hot key, ( \ ) enable multiplex
