Underline key combinations and shortcuts for direct access(Windows Vista, 7)

                While operating menus throughout Windows, you are used to seeing the respective shortcut letters that are characterized by underlines, which help you learn how to quickly use keyboard shortcuts.

                Since Vista, the underlining of shortcut keys in menus for better readability is turned off as a standard setting. This practical and unobtrusive help function can be quickly activated again in the ‘Ease of Access Center’.
                For this, click in the Control Panel on ‘Ease of Access’ and then on ‘Ease of Access Center’. There, follow the link ‘Make the keyboard easier to use’. Activate the option ‘Underline keyboard shortcuts and access keys’. Confirm the dialogue with ‘Apply’ and ‘OK’ one after the other (or ‘Save’ in Vista). The change is active without a restart. However, these underline hints are not present everywhere; they are mainly there in the classic menus and, for example, not in the Windows Explorer toolbar.
