But what I really miss already in the Editor:
* No Text selected / marked: CTRL+SHIFT+Arrow Down or Arrow Up: Move the current single Line of Text (in which the Cursor sits) up or down
* Multiple Lines of Text selected: CTRL+SHIFT+Arrow Down or Arrow Up: Same but moves thew whole selected Textblock up or down
This is actually seems like a nice function, implemented in trunk (would be in nightly in 2 days, or you can checkout svn or git and compile your own).
