The edit menu
Most options here speak for them selves. You'll probably know them from other
programs.
Undo / Redo
If you have made a mistake on an object (text-image) you'll be able to undo your
mistake (just one time - well, it's more than in life). If you find that your
mistake wasn't a mistake at all you can redo it with redo.
Options
Here you're able to select different languages and /or define your own keyboard
- combinations for various actions(like cut/open/print etc).
