Hi, this is Ingo and welcome to Aptana. Aptana not only gives you great content assist on which objects are available in JavaScript, CSS, and HTML, but also helps you know which browsers support those objects. I'll give a brief example.

First, let's open a JavaScript file. Starting here, I'll begin with a sample object, such as document. Here you can see the browers which support each of the individual properties and methods. Some are available in IE only, some in Firefox only, and some in both. In addition, off the righthand side here, we show exactly which version of that browser first supported that object.

Let's say, however, you have a wider user base and want to see Opera or Safari support. First, we go to the Preferences menu and we can add additional browser preferences. Now by doing control+space, you'll see browser support across all four selected browsers.

This support also extends to HTML. First, we'll start by creating a new HTML document. And you can see inside here, if we look at something like the Abbreviation tag, Abbreviation is only supported in Netscape, Mozilla, Opera, and Safari, but not IE. In this way, you can make sure that the tags you're using are supported by the browsers you wish to deploy to. Thank you.
