I also have the problem with my macbook pro 2016 touchbar.
Enabling the function keys also did not help (i enabled it also before).
Some strange thing is, that sometimes the F4 key works, anotherday it does not and i don't know the reason why.
A solution would be nice since i use the qtcreator and switching between .h/.cpp (without changing default keys) is realy importend.
Well, i tryed to set "Send OS X system shortcuts" to "Always" and it worked for now. Thanks to SteveD1.
I hope this works also tommorow
