thanks a lot!

Can someone tell me if there is a smarter way to make unique copies of components (not groups)? I am working on some table variations and it is really annoying when I have to make unique, make unique, make unique, every single copy of the table that I want to modify.

Can anyone tell me if there is a way to change current input method inside sketchup? I am aware that I can change my shortcuts but this doesn't help me much. I would like to have all may commands under my left hand, similar to video games. In autocad I managed to do this and make c-circle, cc-copy, rt-rotate-, rr-mirror etc, and then by pressing spacebar I activate the command. Is this possible by any chance in sketchup? I really hate pressing weird shift+ or ctrl+ combinations
