jQuery highlight clickable areas
<p>I wanted to ask you if there is a way of highlighting clickable items within a basic HTML page, ideally by pressing a keyboard key.
When I build functional prototypes, to save time only some of the functionality is actually developed to show the flow. I want to somehow show which items are clickable, so users don't need to hover every single item to find out what can be clicked.</p>

<p>Ideally what I want to achieve is when a user presses a predefined key, a box appears on top of every link (text or image or map coordinates), and this should be achieved automatically via a script, so that I don't have to set it up manually for every prototype I build.</p>

<p>Is that possible to achieve? Thank you in advance for your suggestions!</p>
