Note:
The History panel is deprecated in Dreamweaver CC 2017 and later.
The History panel records the steps you take when you complete a task. Automate a frequently performed task by replaying those steps from the History panel or creating a new command that performs the steps automatically.
Certain mouse movements, such as selecting by clicking in the Document window, can’t be played back or saved. When you make such a movement, a black line appears in the History panel (the line does not become obvious until you perform another action). To avoid this, use the arrow keys instead of the mouse to move the insertion point within the Document window
Some other steps also aren’t repeatable, such as dragging a page element to somewhere else on the page. When you perform such a step, an icon with a small red X appears in the History panel.
Saved commands are retained permanently (unless you delete them), while recorded commands are discarded when you exit from Adobe Dreamweaver, and copied sequences of steps are discarded when you copy something else
The History panel (Window > History) shows a list of the steps you’ve performed in the active document since you created or opened that document (but not steps you’ve performed in other frames, in other Document windows, or in the Site panel). Use the History panel to undo multiple steps at once and to automate tasks.

Note:
You can’t rearrange the order of steps in the History panel. Don’t think of the History panel as an arbitrary collection of commands; think of it as a way to view the steps you’ve performed, in the order in which you performed them.
-
Note:
To scroll automatically to a particular step, you must click to the left of the step; clicking the step itself selects the step. Selecting a step is different from going back to that step in your undo history.
-
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.
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.
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.
-
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.
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.
Each open document has its own history of steps. You can copy steps from one document and paste them into another.
Closing a document clears its history. If you know you will want to use steps from a document later, copy or save the steps before you close the document.
-
Note:
The Copy Steps button in the History panel is different from the Copy command in the Edit menu. You can’t use Edit > Copy to copy steps, although you do use Edit > Paste to paste them.
-
The steps are played back as they’re pasted into the document’s History panel. The History panel shows them as only one step, called Paste Steps.
If you pasted steps into a text editor or into Code view or the Code inspector, they appear as JavaScript code. This can be useful for learning to write your own scripts.
.Save a set of history steps as a named command, which then becomes available in the Commands menu. Create and save a new command if you might use a set of steps again, especially the next time you start Dreamweaver.
-
Note:
The command is saved as a JavaScript file (or sometimes an HTML file) in your Dreamweaver/Configuration/Commands folder. If you are using Dreamweaver on a multiuser operating system, the file is saved in the specific user’s Commands folder.
Record a temporary command for short-term use, or record and save a command to use later. Dreamweaver retains only one recorded command at a time; as soon as you start recording a new command, the old command is lost, unless you save it before recording the new command.
