11 :: What are your tools of choice to get the jQuery job done?

For editing files, I love the e texteditor (yep, the name is “e”). It basically started as a textmate clone for windows, but since then grew into something much greater. One of the features I can’t live without now is there great multiple selection support. Hold down CTRL, select a couple words through double clicking and then type over all of them. Is that cool or what? On a sidenote, on one of my talks in Japan the audience asked why I’m so insane to use a Textmate clone through an emulated Windows on OSX - I showed them this exact feature, and they were all amazed.
