The left hand pane of the Keyboard Manager contains an alphabetical list of all the current application key map files plus the default key map file. You can use your UP and DOWN ARROW keys to move through the list of files. You can also type a letter to select the first file in the list that begins with that letter. Each time you type the letter, the next file beginning with that letter is selected. You can continue this process until no file names match the letter you are typing. The Keyboard Manager displays the contents of the currently selected file in the right hand pane of the manager.
When you find the desired key map file, press TAB to move to the right hand pane and review the information contained within that file.
