Go check out knowhow, a new technology preview now posted on the Adobe Labs.
What is knowhow?
knowhow provides single-click contextual access to relevant help information on a particular topic right from within your desktop application: this includes direct access to basic information, such as short descriptive text and available short-cuts, Adobe Help content, and highly relevant online community-generated content. knowhow pulls its community-generated content from a user account on del.icio.us. The knowhow user experience was built entirely in Adobe Flash, in a panel that is currently included within Adobe Illustrator CS3 (Universal and International English builds only), and also embedded in a browser page for tryout on Adobe Labs.
