Using the History palette

You can set the maximum number of states that the History palette displays for a page or site (20 states by default). When you switch between open documents or site windows, the contents of the History palette adjusts accordingly. However, the content is cleared and you lose the information when you click a different tab in the document window.

To use the History palette:

1. Choose Window > History.

The History palette lists the previous states of the document, the oldest state at the top of the list and the newest state at the bottom.

2. In the History palette, click the state of the document to which you want to revert.
3. To restore the changes that you made to that document state, choose a newer state in the History palette. (The newer states of the document are dimmed.)

In Mac OS, press Shift+Command+Z to restore the changes that you made to a document state incrementally. To discard all of the changes to the document listed in the History palette, press Option+Command+Z, and then click Discard.

To set the maximum number of states listed in the History palette:

In the History palette, choose History Options from the palette menu, enter a number between 1 and 1600 in the Maximum History States text box, and click OK.

To clear the History palette of all states:

In the History palette, choose Clear History from the palette menu.
