I remembered ctrl-c/v worked on 10.9, maybe in SampleWindow. Does right click 
show copy/paste? I'm not able to test on Mac recently.

I am on 10.8.5. I cannot confirm on 10.9

The right-click copy/paste works. But not Ctrl-c/v

I tested on Mac 10.10 and it couldn't ctrl-c/v. I forgot how it might worked 
before. (Turns out ctrl-backspace/left or right arrow works.) I might look into 
this later.
