How do I enable the mnemonics (underlines) being displayed when an application is launched ?

Usually the underline appears only after you press the Alt Key, but you can enable it by changing the Operating System Settings. On Windows XP, Right Click ‘Desktop’ to bring up the Display Properties Dialog, then click on the ‘Appearance’ tab and finally on the ‘Effects’ Button and uncheck the checkbox ‘Hide Underlined letters for keyboard navigation until I press the ALT Key’.
