Supressing Default Form Submit on [ENTER]

Problem is - when you hit <ENTER> form gets submitted,
 but in most cases you need to run, let's say, AJAX and just "automate" text box so it initiates AJAX w/o form submit.
This is very easy to do with jQuery that shields you from tedious cross-browser nuances:

$("#tbDoSearchText").keydown(function(e) { if (e.keyCode==13) {$("#btnDoSearch").click(); e.stopPropagation(); return false; }});

Where:
   tbDoSearchText - is your text box with user search terms text,  btnDoSearch - the button that runs AJAX search "onclick"

I have bolded important part.

Thats it -  when user enters search text and hits <ENTER> - "onClick" is called and AJAX starts (assuming you have an AJAX call in button click event)
