This just work for me (cc2015 osx10.10.4)

KeyEd Up doesn’t work here because it is missing a file
The file that the script was missing has a different name in AE CC (aka version 12.0)…
So you really need to go to Terminal first and ask your Mac to always show you the Library, by typing:
chflags nohidden ~/Library/
And then when launching the script in AE, when it says it can’t find the shortcut file, it is because it has a different name than what the scripts expects. The next window it asks you to locate the file (that is why you need this Library to be accessible).
it is under Users/yourname/Library/Preferences/Adobe/After Effects/12.0 (or 13 or 13.5…)
Adobe After Effects 12.0 Mac en_US Shortcuts.txt (or 13 or 13.5…)
Once you selects this, KeyEd Up lunches and finally works the way it should.
