Undo is used to reverse any action done by the user, just before.

Undo erases the last change done to the document reverting it to it's older state.

$\large{\red{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\underline{\underline{\underline{Hope \:it\:helps\: you}}}}}}}}}}}}}}}$

Answer 2

To reverse your last action, press CTRL+Z. To reverse your last Undo, press CTRL+Y. You can reverse more than one action that has been undone. You can use Redo command only after Undo command.
