Sadly, none that I’ve come across. As Vermonter indicates in his excellent blogs, the early stuff is fairly straightforward, but after a certain point the application becomes sharply more complex. See “Notes Blizzard” in the “And Now for that Latte” section of this forum for a discussion of why such complexity may be intrinsic to the power of the software.
However, there are signs that Eastgate is listening to users who are seeking more guidance and tuition on not just the simple bits but the more complicated stuff as well. Meantime, if you find the manual too terse, I strongly recommend downloading Mark Anderson’s aTbRef5 folder, either as a Tinderbox document or HTML folder (which Safari can search), reading it first from top to bottom and then searching it when you hit a problem. It may bewilder you first time round, but then very gradually become more comprehensible.
