advertised-undo

advertised-undo is an alias for `undo' in `simple.el'.


(advertised-undo &optional ARG)

This function is obsolete since 23.2;
use `undo' instead.

Undo some previous changes.
Repeat this command to undo more changes.
A numeric ARG serves as a repeat count.

In Transient Mark mode when the mark is active, only undo changes within
the current region. Similarly, when not in Transient Mark mode, just C-u
as an argument limits undo to changes within the current region.
