If I had clear cut repro steps I would post a bug. I've just had mixed results. Plus it might be nice to have a "holding pen" to move stuff in and out of. Also, sometimes I over-select and if the menu bar said "20 items copied" instead of the 4 I wanted, I would know I made an error. This keyboard has a dumb function key where CTRL should be. I probably hit it on accident, but without any feedback I don't know that I didn't copy anything. (maybe I'll pry it off. I never use it.)
