@rdelhaise-wiiisdom This may be a computer settings issue rather than an Electron issue. In your Settings menu of your computer, under Accessibility > Keyboard check to see if the option "Underline access keys" is on. If it was off, you should be able to turn it on and now be able to see the access keys underlined in your test. When the option is off, you should also be able to see the access keys underlined by pressing the Alt button.

Was your issue resolved by turning this option on?
