Updating JScript IntelliSense
Keyboard: CTRL + SHIFT + J
Menu: Edit -> IntellisSense -> Update JScript IntelliSense
If you find that your IntelliSense isn't showing items for JScript items you recently put in then you can update the JScript Intellisense yourself by going to Edit -> IntellisSense -> Update JScript IntelliSense or pressing CTRL + SHIFT + J:

When it is done, you should be able to see the newly added items in your IntelliSense.
