The Edit menu provides standard editing functions, as follows:
Again repeats the last editing action.
Undo undoes the last editing action or all editing
actions, depending on which item you choose from the Undo submenu.

of the clipboard are overwritten with the new information.

the insertion point.
Cut removes the selected text and stores it on
the clipboard. Only one selection can be stored on the clipboard at a time.
