When I do a rename of a file (or a folder) I want to be able to use copy/paste (CTRL+C / CTRL+V) !
When I try to do this (using keyboard shortcut or right click), the name gets validated (I am not in edition mode anymore) ... so I can't copy the name ! :(
As soon as I right click or use the CTRL key, the name is validated: I am not in edition mode of the name any more and that's the file that is selected and not the file name anymore.
EDIT: Sept 2016
This was due to the option to display circles when pressing CTRL (Parameters=> Mouse check Reveal cusor position: that stops the edit mode as soon as you press CTRL) !
This is still true for Loki.
