Hello Zhihong,
same story here: only backspace triggers the binding (I raised the issue in the past too). I'm currently on PS CC 2014 release, OSX 10.9.3
Matt's extension installs only on CC, but I had a couple of similar extensions of mine that are functionally wrong in the same way on CC 2014 too - bad keyDown events.
Any help is appreciated!
Thanks,
Davide Barranca
