JS: Performing another keypress event

Question

Suppose I press the Tab key, I would want that it performs another action besides the default event. I've selected a text box and I want it to add some spaces (Just wanting a textarea to act like a text editor). How to trigger this type of event?

So far, I only know how to prevent the default action:

 $('#content').on('keydown', function(e) { if(e.which == 9) { e.preventDefault(); }});

But how do you fire another keyboard event?

This is concatenating the spaces, therefore the spaces are being found at the end of the whole textarea. — Olivier S

Yes, if you want to add the spaces at the caret, that's not really hard to do, there are hundreds of answers on SO on how to do that. — adeneo

There is no need to preform any action. Just change value manually: LIVE DEMO

$('#content').on('keydown', function(e) { if(e.which == 9) { var val = $(this).val(); val += ' '; $(this).val(val); e.preventDefault(); }});
