Edit>Undo (shortcut: C+z
) reverses the
most recent editing command. For example, this can be
used to restore unintentionally deleted text. More complicated operations,
such as a search and replace, can also be undone.
If you undo too many changes,
Edit>Redo (shortcut:
C+e C+z
) can restore
the changes again. For example, if some
text was inserted, Undo will remove it from the
buffer. Redo will insert it again.
By default, the last 100 edits is retained; older edits cannot be undone. The maximum number of undos can be changed in the Editing pane of the Utilities>Global Options dialog box; see the section called “The Editing Pane”.
