Dreamweaver from the 3.0 version, the new History panel features. The so-called History panel, is the operation of the steps to save, can restore or repeat history. In fact, this historical panel is to borrow the famous image processing software Photoshop History panel concept.
To open the history panel, you can either click the Laucher panel's penultimate icon, or use the shortcut key F9, or click Window\history on the menu bar.
Our edits to the page will be recorded in this history panel. Each step of the operation, the panel will be more than the corresponding record. The record on the left has a slider to slide up and down, and the place where the slider stops is the current step.
Select a record and click on the "Replay" button to repeat the current action for the record you selected. Of course, you can also use the CRTL or SHIFT key, plus the mouse to select a number of records, and then click the "Replay" button to repeat the multi-step operation.
Alternatively, you can select one or more records, click the button in the lower-right corner of the history panel, save to the Clipboard, and use the CTRL + V key to repeat the actions that these records represent. The benefit of saving to the Clipboard is that you can also repeat the saved content to another page.
Alternatively, you can select one or more records and click the buttons in the lower-right corner of the history panel to take the actions represented by these records as a command in the menu bar. This command in command will be executed directly in the future.
If you want to go back to the previous operation, you can move the history panel slider directly to the corresponding record.
