After running my site through powermapper tools, they present this issue:
All ONCLICK handlers should have an equivalent ONKEYPRESS handler. Section 508 1194.22 (l) WCAG 2.0 A F54
Some users are unable to use a mouse, so use the keyboard instead. Add an equivalent keyboard event handler to help these users.
My question then is, what is the standard way to craft buttons to identify the keyboard-only users what key to press to use a button? Should I follow the Microsoft Windows format where the key to press is underlined in the button name, or is there a better way to do this?
