Peter S updated NETBEANS-3705:
------------------------------
    Description: 
So this one was a bit fun to narrow down.  I thought it was the keyboard at 
first, then maybe read-only file, but other files work and restarting didn't 
solve the problem.
h3. Symptoms

Loss of TAB and RETURN/ENTER key functionality.
h3. Cause

I've narrowed the problem down to this piece of PHP:
{code:java}
<?php

$pattern = '%<a.+?style="(?<style>.+?)".*?>(?<value>.+?)</a>%';

$str = '<img';

if (preg_match('%/(\d+)/0%', $str))
    $k = '';

{code}
Removing any of the above lines seem to solve the problem.

 

All other keyboard keys and commands seem to work, including copy and pasting 
line-breaks and tabs.
