Undoing Changes
Some adverse results are obvious, like a delay in a project finish
date after you change the standard work time. Most of the time, though,
as in a game of chess, you can’t tell whether a strategy will pay off
until you’re a few moves in. Multilevel
Undo, introduced in Project 2007, lets you try short what-if games in
your current Project file. You can backtrack through any number of
actions if they don’t pan out.
Note
You can specify how many actions Multilevel
Undo remembers. Choose File→Options. In the Project Options dialog box,
choose Advanced. Under General, in the “Undo levels” box, choose the
number of actions to track (up to 99) and then click OK.
Multilevel Undo keeps track of your actions and displays them on a
menu so you can select the ones you want to undo. Here’s how to put
Multilevel Undo to work:
-
On the Quick Access toolbar,
click the down arrow to the right of Undo (which looks like a curved
arrow sweeping from right to left).
A drop-down menu appears, listing your previous actions with
the most recent at the top to the earliest at the bottom. Project
clears the Multilevel Undo list when you save your Project file or
close and reopen it.
-
To undo actions, drag down to the earliest one you want to undo.
Project highlights the actions from the most recent to the one where
the pointer is. The last entry in the drop-down menu says “Undo x
Actions”, where x is the number of actions you’ve selected, as in Figure 8.
If you’re a prolific editor, you may see a few recent actions and a
scroll bar on the drop-down menu. Drag the slider until you reach the
earliest command you want to undo, and then click to revert to that
point.
-
Click the earliest action to undo the recent commands up to and including the action you clicked.
Multilevel Undo can unravel everything a macro does, or reverse changes that other applications make to your Project file.
