view command box

new user
I did something and my command box disapered. How can U get it back?
Also how do I clear out the copy buffer? each time i try to paste it still has the original object in it instead of the new one I want to paste.

hi,
try "widgets >> dock widgets >> commandline"

Maybe you miss selecting the reference point for copy, then the copy cycle is interrupted and the old clipboard content stays valid.
