F16 works, but not the three others. However, I tested assigning other things to F17-19, and those do work – so there’s not a conflict there. Any reason why PBD might not work on those? I’d like F19 because it’s ergonomically comfortable and easy for me to remember.
I previously had F19 assigned to open “Expression Maps” window which it was working with great success. I removed it though, before re-assigning, so nothing is assigned to it any longer. However, if I were to re-assign that to F19, it works. So it seems for some reason ‘toggle PBD’ does not like that key.
I’m on a mac, F19 does not appear to do anything in any other context (and I had no conflict otherwise before). Does anyone know of a mac utility perhaps where I can monitor any keyboard messages across the system, as a way to spy for any conflicts?
