Undo multiple steps at once
Drag the slider to point to any step, or click to the left of a step along the path of the slider.
The slider scrolls automatically to that step, undoing steps as it scrolls.
Note: As with undoing a single step, if you undo a series of steps and then do something new in the document, you can no longer redo the
undone steps; they disappear from the History panel.
Set the number of steps that the History panel retains and shows
The default number of steps is sufficient for most users’ needs. The higher the number, the more memory the History panel requires, which can
affect performance and slow your computer significantly.
1. Select Edit > Preferences (Windows) or Dreamweaver > Preferences (Macintosh).
2. Select General from the Category list on the left.
3. Enter a number for Maximum Number Of History Steps.
When the History panel reaches this maximum number of steps, the earliest steps are discarded.
Erase the history list for the current document:
In the History panel’s context menu, select Clear History.
This command also clears all undo information for the current document; after choosing Clear History, you can’t undo the steps that are cleared.
Clear History does not undo steps; it merely removes the record of those steps from memory.
Repeat steps
Use the History panel to repeat the last step you performed, repeat a series of adjacent steps, or repeat a series of nonadjacent steps. Replay the
steps directly from the History panel.
Repeat one step
Do one of the following:
Select Edit > Redo.
In the History panel, select a step and click the Replay button. The step is replayed and a copy of it appears in the History panel.
Repeat a series of steps
1. Select steps in the History panel:
To select adjacent steps, drag from one step to another (don’t drag the slider; just drag from the text label of one step to the text label of
another step), or select the first step, and then Shift-click the last step.
To select nonadjacent steps, select a step, and then Control-click (Windows) or Command-click (Macintosh) to select or deselect other
steps.
The steps played are the selected (highlighted) steps, not necessarily the step the slider currently points to.
Note: Although you can select a series of steps that includes a black line indicating a step that can’t be recorded, that step is skipped
when you replay the steps.
2. Click Replay.
The steps are replayed in order, and a new step, Replay Steps, appears in the History panel.
Make or extend a selection
Hold down the Shift key while pressing an arrow key.
If a black mouse-movement indicator line appears while you’re performing a task you want to repeat later, you can undo back to before that
step and try another approach, perhaps using the arrow keys.
Apply steps in the History panel to objects
You can apply a set of steps from the History panel to any object in the Document window.
If you select multiple objects and then apply steps to them from the History panel, the objects are treated as a single selection and Dreamweaver
attempts to apply the steps to that combined selection; however, you can apply a set of steps only to a single object at a time.
To apply the steps to each object in a set of objects, you must make the last step in the series select the next object in the set. The second
procedure demonstrates this principle in a specific scenario: setting the vertical and horizontal spacing of a series of images.
Apply steps to one other object
