About your first comment.
Apptivate works in this way: say that i have dozen of scripts, and 4 of them are related to my NAS, so i assign the same keystroke OPT+SHIFT+N to these four scripts since the letter N reminds me of NAS
However if i type such keystroke, Apptivate does not know which script to launch out of the four, so i can assign a second key to be pressed to select which one
Say that 2 of those scripts are referring to the folder VIDEO on my Nas, then i can assign the second key V to both of them
