How to define a component hotkey on a page
I remember someone asking, how do I set a hotkey? In fact, as long as we pay careful attention, on many controls have a can be used to define the key on the page properties, it is "ACCESSKEY." For example, there are on the button, in the <TABLE> have, in the <LABEL> have, in the picture also, and so on.
It is simple to use, such as the <LABEL> can be defined as:
<label for= "Namebox" accesskey= "N" > Name (<U>N</U>):</label>
<input type= "TEXT" id= "Name" size=30> <br>
Then the hotkey to access this component is "Alt+n".

What, have you noticed?
