Illustrator enables you to undo changes you ve made, redo changes you ve undone, and revert to the last saved version of a file if you ve messed up the open version too badly .
Illustrator not only supports extra keyboard shortcuts for Cut, Copy, and Paste operations but also offers keyboard shortcuts for pasting in front and pasting in back. You can also start a spelling check, invoke help, and start configuring Illustrator from the keyboard.
