That's what I thought; but I stopped using that tool some time ago, 
because it often failed, either in process or when doing further 

I think the ability to go to a keyframe is valuable and should be kept - 
and preferably improved - but I sometimes overshoot the mode into 
'cutpoint' - and wish I hadn't.  There was a thread about the mode 
switch options maybe a year ago but it died out.  For use from the 
keyboard PgUp and PgDn give 'cutpoint' too, so its place in the mode 
sequence isn't vital, but it may be needed for use with a remote.
