In future, I'll hide them more thoroughly. ;-)
Anything not in the manual is a 'work in progress' and almost certain to
change.
In the case of 'set tbase', it'll be split into multiple events so you
can avoid unexpected waltzing.
And 'set drctn' will have a variant to avoid the random settings.
Although I have become rather partial to patterns that are half
'forward', then half 'random'.
