The History palette shows a list of all the steps you've performed in the active document since you created or opened that document. (The History palette doesn't show steps you've performed in other frames, in other document windows, or in the Site window.) It allows you to undo one or more steps; it also allows you to replay steps and to create new commands to automate repetitive tasks.
The slider, or thumb, in the History palette initially points to the last step that you performed.
Note: You can't rearrange the order of steps in the History palette. Don't think of the History palette 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.
To set the number of steps that the History palette retains and shows:
| 1 | Choose Edit > Preferences and select General from the Category list. |
| 2 | Enter a number for Maximum Number of History Steps. |
| The default value should be sufficient for most users' needs. The higher the number, the more memory the History palette requires. If you exceed the maximum number of steps you set for the History palette, the earliest steps are discarded. | |

To erase the History palette's history list for the current document:
In the History palette's context menu, choose Clear History.
This command also clears all undo information for the current document; after choosing Clear History, you will be unable to undo the steps that are cleared. (Note that Clear History does not undo steps; it merely removes the record of those steps from Dreamweaver's memory.)
