we have an idea about Baby Jane, but whatever happend to esc,t,m,d?

My fingers seem to remember this as a shortcut for moving round tables (move down to cell below) … but while t,m,n and t,m,p are still enabled for next and previous, 'up' and 'down' seem to have disappeared. Is there anything a mere user can do about this?

This is in FM 10; if the request approved in July ever comes to fruition, I could be moving to FM 12 Real Soon Now, and even getting Admin rights so I can cautiously make tweaks.
