If you go to `http://[site]/users/[userID]/[username]?tab=activity&sort=revisions` (e.g. on this site it would be https://meta.stackoverflow.com/users/256858/user3439274?tab=activity&sort=revisions for you) you can see all the edits you have done to any post. You can get there by going to your user page, clicking on the <kbd>activity</kbd> tab, then clicking on the <kbd>revisions</kbd> sub-tab.
