I would use an auto complete thing if it worked ;) ... is this like intellisense?
Kind of - just basic keyword completion and also keywords from within the file you are in at present. It appears when you hit ctrl+space. (hmm, must check if you can change that shortcut...)
The known issue is that on mac & linux there is no way at present (*looks for sebholl and brucey*) to grab the text cursor position in a textarea. As such, the pop-up window rather naffly appears at the mouse cursor instead. Why it's showing at startup is a mystery...
