My favorite text/programming editor is UltraEdit, for years now. And with each release, it's getting even better with great new features. The features I like best are the SFTP support and the column-selection modus.

As a developer (mostly) on PHP sites, I often check the PHP manual and search on HTML-tags and CSS reference @ w3schools.

To do this more quickly I have created some easy "UltraEdit Tools" which are based on Google's "I'm feeling lucky". The tools will redirect to the manual or reference. When having selected a word (i.e. a php function, tag, or css selector), it will go directly to the corresponding page (tries it anyway).

You can find the command-lines for the tools in my forum post @ IDM

[update]There's even a nicer way to do it, as 'jorrasdk' replied on my post[/update]
