Correcting mistakes
You can use the Undo command to
correct mistakes you make while using
the Adobe Illustrator program. You can
even undo an operation after you have
chosen the Save command (but not if
you have closed and then reopened the
file). If an operation cannot be undone,
the Undo command is dimmed.
Depending on how much memory is
available, you can undo up to 200 of
the last operations you performed, in
reverse order, by repeatedly choosing
the Undo command. Illustrator’s perfor-
mance is usually not affected by the
number of undo levels you choose;
however, if you are trying to display
complex artwork, you may receive a
message asking you to reduce the
number of undo levels because of
insufficient memory.
The default undo level is set at 10.
You can set the number of undo levels,
between 0 and 200, in the General
Preferences dialog box.
