Actually, WordStar on the Osborne 1 didn't come configured for any
of the features of the machine; it was just shipped as plain vanilla,
as far as I could ever tell. For example, the arrow keys on the machine
were set up to deliver CP/M codes, and you had to do a messy setup
operation to switch back and forth between those and the codes that
WordStar expected.

I found it much easier to use after I dug into the customisation
info, and set the screen help delays etc to what I thought were
sensible values. I also found and published a patch for the arrow keys
problem, but that's a longer story ...
