Exactly. But it is not well defined yet out there in the web 
if keyboard usage should be announced as part of the element info in tooltip 

a) always for all keys (I think this is not necessary)

b) for some keys only (the case I mentioned for tabstrip) and rest navigation be covered by FAQ or Best Practices

c) also for hotkeys if shortcuts are available in title of images in toolbar (e.g. CTRL+ALT+P for print)

In addition, should this help be
a) always present
b) on user request, configurable by user (personalization)
c) keys overridable by users if they enter problems on their browsers

Last ones b) c) are maybe something for the XHTML2 working group's personalization concept also ...

- Stefan

s/memorizing/explaining

The tooltip explains the special keys to users not familiar with them  
yet.

Is that right, Stefan?
