Try these multi cursor tricks:
Highlight some text or cursor over a word that appears multiple times in a document, then press Ctrl-D repeatedly (or Alt-F3 once). Now edit them all at once.
Highlight a paragraph, then use Selection->Split Into Lines to get one cursor/selection per line. Now hit Home a couple times and start typing to prefix all the lines simultaneously with text.
This also works in concert with the Ctrl-F find function (Find All) and functions as a sort of "live" search-and-replace.
Just experiment, I think you will find many time-saving uses for this functionality, though it does take a bit to rewire your brain accordingly.
