Variable: cua-highlight-region-shift-only
cua-highlight-region-shift-only is a customizable variable defined in
cua-base.el.gz.
This variable is obsolete since 24.4; use transient-mark-mode(var)/transient-mark-mode(fun)
instead.
Value
nil
Documentation
If non-nil, only highlight region if marked with S-<move>.
When this is non-nil, CUA toggles transient-mark-mode(var)/transient-mark-mode(fun) on when the region
is marked using shifted movement keys, and off when the mark is cleared.
But when the mark was set using M-x cua-set-mark (cua-set-mark), Transient Mark mode
is not turned on.
Probably introduced at or before Emacs version 24.4.
