The general rule applies also to byte-compilation etc.
But it's a general rule.  What matters in the end is
usage.  If a particular writing of a composite word
becomes most common then that's it.  It's not unusual
to see an evolution from xxx yyy to xxx-yyy to xxxyyy.

The general rule is that when used as a noun it's a
noun phrase, and is written as separate words.  When
it's used as an adjective before a noun it's written
with a hyphen.  So:

"This happens during byte compilation."
"Byte-compilation optimization happens on Tuesday."

It's fine to decide whatever style you like.  It's
generally good to then be consistent in using it, of
course.

The reason for the rule is for readability: ease of
parsing when used as an adjective.  Nothing more.

In any case, I'd still suggest a glossary entry for
shift selection (or shift-selection, if that's your
decision).
