Update: This appears to be on a different port for others. As Jax pointed out you can go: Eclipse, select Help -> Help contents to get there as well :o)I was just going into some help files of Aptana when I came across the local address for the Eclipse Help system at:http://127.0.0.1:58041/help/index.jspIn there was a wealth of information I just didn't know was on my hard drive ... though I suppose it depends on what plug-in's you've got installed but for me I had: references and getting started tips for Subclipse, plus ColdFusion Documentation, Using CF extensions for Flex builder (including details of RDS support), Java development user guide, plug-in guide and loads more. The Aptana section is indepth as well with documentation covering:
Ajax Libraries (including Spry 1.5
CSS (elements and properties)
HTML
Javascript (keywords, DOM, core)
and even javascript reference for Adobe AIR(though that seems to actually hit Adobe.com livedoc (which is slicker than the CF ones!))
