Keyboard navigation and transparency with Enhanced DataTips
Steve Steiner recently blogged about how to make DataTips temporarily transparent in case you need to see what they might be covering up. This was going to be one of my upcoming tips, but he beat me to it! :) Anyway, with that post he touched on another aspect of DataTips that you might not know about -- they have some limited keyboard support. To get access to it, you first must expand a top-most tip one level via the mouse.
From there you can:
There is certainly room for further improvement. In particular, I would have like to have implemented the ability to invoke a DataTip via the keyboard and to support [home] and [end] for scrollable tips, but time constraints cut that effort short. Hopefully, you'll see more in a future release!
