One of the most common tasks in Audit is marking a commit as accepted, but there's no quick way of doing so. You have to scroll to the bottom of the page (or press z), change "Action" from "Comment" to "Accept Commit", and press Submit.
Possible solutions:
* An "Accept Commit" button at the top and/or bottom of the page
* A shortcut key that scrolls to Creative Account, sets action to "Accept Commit" and sets the focus to the comment box or to the Submit button
