How to add a underscore to indicate users what is the shorcut key of Button?

Under Winform, our can add & symbol on label to indicate what is the
shortkey of button, in ASP.NET, how should I to do that?

 

[Kevin Spencer]

Create a button with an image background. Make the image background look
like a button face with an underline under the character you want to
indicate as a shortcut key.
