@Fjordaan: The worst part is, the Ctrl-X/C/V set was apparently chosen because those letters were 'conveniently' placed close together. And an example from the world of the command line: The crontab command can take three options, two of which use letters placed right next to each other on the keyboard: -e says: please edit my crontab file, while -r says please ... delete my crontab file. Of course there is no undo. The third option is -l for list. What a relief you're never going to type that one by accident.
