Hello,
Thanks a lot for taking the time to detail your way of doing … unfortunately, that still doesn’t work for me 
I’ve tried anything I could think of when bashing Ctrl / Alt / Shift keys, and it’s still the same when switching back to UE ! I hope we’ll hear something from Epic one day, because it’s really a pain not to be able to use shortcuts for view modes
Thanks again for your help,
Cheers.
