On the Authorise Features for Role option for highlight to default to Filter button

When amending Roles and searching for features, you can type in the Feature Name field to look for a word that will help you find an option easier. However the button highlighted by default is OK, so if you type and press Enter, it closes the form. Can you default the highlight to the Filter button, so if you're pressing Enter then it will filter. I cant see a good reason for the highlight to default to the OK button. And it will save me a lot of time!
