Using the incremental attribute to detect keystokes

One of the slickest application genres are those that update data as you type. XForms does this with finesse! Controls have the ability to send events after each keystroke entered within them using the incremental attribute. That way controls that need to change their data based on the data of a control that's changing incrementally can also update their data incrementally, effectively keeping what's viewed "on screen" in sync across the board. This tip shows you how to make the most of the incremental feature with sample XForms code.
