Multi trash buffer
You can use e.g. ^T "delete right word" and ^U "paste deleted word/line" several times and move e.g. several words or lines. But if you move the cursor between several ^T keypresses, the multi-undo is no more available. It also works with ^Y "delete line": you are able to move whole pararaphs by this way.
Sample:
one two five six three four seven
Place the cursor at the beginning of 'five'
press Ctrl-T Ctrl-T to delete two words
place the cursor at the beginning of 'seven'
press Ctrl-U Ctrl-U to eject the two words at the current cursor position
