You'll want to open up Firebug for this

Click each of the items below to run the command:

• dojo.require("dojox.help.console");
• dojox.help.locate("xhr", dojo); searches variable names in the dojo namespaces for "xhr".
• dojo.query.help(); displays help for dojo.byId
• dojo.connect loads and displays the function signature for dojo.connect
• dojo.isBrowser shows an example of a "conflict". It's using the Boolean object rather than the boolean generic.
• dojox.help.noConflict(); fixes this conflict (click on dojo.isBrowser again).
• dojox.help.refresh(); parses the page again
• dojo.isBrowser and the conflict is back again!
