Complete list of hardware keyboard shortcuts for Desire Z?

Question

I like to use the hardware keyboard of the Desire Z including shortcuts, however I haven't found a complete list. For example, the HTC help pages don't mention Function + Backspace = Deletion of text left to the cursor.

Can anyone provide a complete list or further "secret" shortcuts? This might also involve the usage of the optical "trackball", e.g. selecting text by using it while pressing Shift.
