Introduction
All editable pages have an associated page history, which consists of the old versions of the wikitext, as well as a record of the date and time of every edit, the name of the user who wrote it, and their edit summary. Access the page history by clicking the “history” tab at the top of the page. This may also be referred to as the revision history or edit history.
Linking to a specific version of a page
It is occasionally useful to link to a specific version of an article (a snapshot of it). For example, one might have done a review of an article and want to indicate which particular version was reviewed.
If the version is not the current version, one can use the page history to view the old version of the page. The URL of this old version is suitable for use to permanently reference this version, and can usually be obtained from the browser’s location bar.
Reverting a page
If your new pages edits aren’t to your liking, don’t panic; you can get back to a previous version in a few steps.
Step 1: View the version of the page that you want to go back to by clicking on the date of that version.
Step 2: Select the text of that version and make a copy of it by holding down the control and ‘c’ buttons on your keyboard.
Step 3: Click on the ‘Article’ tab above to go to the current file.
Step 4: Click on the ‘Edit’ tab. Select the text there and then hold down the control button and click the ‘v’ button on your keyboard to paste the text you previously copied.
