Hello, I just installed the trial version, and I can only set one action. Is it a limitation from the trial version os is it just me ??? 
there are no limitations in the trial version
What exactly are you trying to set up?
Thank you for your quick answer 
Same as the first action that works fine, I try to open a folder with F16 F17 F18 & F19 from the apple extended keyboard
Looks good, so you mean one of the F-Keys works but the others do not? Which one does work?
F19 works, and it was the first I set. All the others don't...
