Re: Transient Mark Mode on by default

[Thomas Lord]

In general, 90% of the (presumably) desired behavior
of shift-select is from a user perspective "A way to
invoke some other command in a special context."

A tiny number of commands in those other applications
are in any way aware of shift selection but, mostly,
it's just built into how text works.  (At least from a user
perspective.)   Invoke *any* command in the right dynamic
context and the selection DTRT.   So just give the user
a means to invoke that special dynamic context.

The code should reflect that.    It's mostly a way
commands can be invoked, not a property of each
and every command.
