Doc? is a free desktop Application, made entirely in FLEX & AIR. Doc? allows you to view your Flash documentation outside of Flash. This enables you to view, search and bookmark your documentation a lot faster than you could with the built in Flash support.
Doc? is a free application. To make using Doc? even more pleasant, the creators of Doc? created some plugins for Flash CS3/CS4 and Eclipse.
I know there are people working on for a nice FlashDevelop support (I really love FD 🙂 ), but I’m impressed by the easiness of the app. It really works fast and looks clean. It’s also a feature to add ASdocs. So mostly every (flash-)documentation can be added.
