Accessibility as well as usability would be enhanced by allowing the user to move focus to the items in a list by pressing the first letter of the item. In other words, user wants to select "Resources" from tools list. When he is in the list, pressing the letter R will move focus to items starting with R, such as Resources and Roster. By continuing to press the letter R, user can cycle between those two items. This is a helpful feature in Firefox, and can be experienced by going to the bookmarks list and pressing an alpha key.
