Hi Sirano, Normally the past command is highlighted and gets replaced by the next command automatically, so does not cause problems. However, if you click in the Command area the highlighting is lost. I recommend if you go to some other window and then come back to the main window, just click in the graphics area (and not the Command area) so that the highlighting will not be lost. However, if the highlighting is lost, you can still use Ctrl-u to erase the contents of the Command area. Ctrl-u erases the command line contents, Ctrl-p switches to the previous command, and Ctrl-n switches to the next command; further text-editing shortcuts are system-dependent: <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/keys.html#textedit> I hope this helps, Elaine ----- Elaine C.

After entering a command in the “command line” of UCSF-Chimera, I would like the command that I pasted to disappear. Currently, it does not disappear; how can I make it disappear after I press the enter button?
