Using the History List

The History tab contains all the changes you have entered as you type your regular expression. The history list appears on the History tab. It stores the regular expression name, the regex string, and the date and time the edit was made. To go back to a previous entry, highlight the line you wish to go back to, and click on the Get button in the lower right corner of the tab. You will be prompted to ensure that you are to replace the regex with the specified one. Choosing Yes will bring back the specified regex. You will also be returned to the Test tab.

To clear the list, click the Clear link in the upper right hand corner of the tab.
