Hi Günter
There really is no generic "Start Recording" key, as you must
launch it from the application itself. However, while you are in
the process of recording, I believe you may click the Pause/Break
key to pause as well as resume a recording in progress.
The Full Motion Recording keys start and stop Full motion
recording. This is separate from normal recording. Generally used
for brief bits such as dragging a window from here to there.
Dragging the thumb of a scroll bar. Or possibly dragging to select
text.
Cheers... Rick
