create short cut keys

hi im new to php i want to know if u are able to create short cut keys in php eg if u create a button and want to use a keybord to go to that button rather then a mouse, for instance u can use ctrl u to go to the button called update .i know in vb u can use &update and u will be underlined..it will emulate a mouse click on update

This makes no sense for me when talking about PHP, but you can do it using JavaScript. Take a look:
