Idea Summary
New Page Item Attribute to initiate the click behaviour of the Item, with an underscore in the item  

Use Case
When there are multiple buttons or tabbed regions, having a short cut to activate the submit or select feature would help users. We are migrating from forms, the default behaviour of shortcuts in forms is missing in APEX. We are building custom Javascript for it. Would be helpful if this is built in part of APEX framework

Preferred Solution (Optional)
Lets say if my Button Label is save, If we provide the formatting as S{a}ve, then ctrl+a should trigger the default behavior of button as submit. The Button label should be displayed with an underscore on ‘a’.
