You can now "type ahead" to select items in hierarchical lists, such as in the Set Menu Keys dialog and File Group windows. This means you can type the first few letters of any visible item in the list to select it. Note that you cannot use "type ahead" to select items which are not visible (because their parent item is not expanded).

Is this function simmilar to Windows' HomeSite auto-tag-complete function? Say you start typing a tag and a pop up menu appears with possible ways to complete the tag.
