Variable: flyspell-check-changes
flyspell-check-changes is a customizable variable defined in
flyspell.el.gz.
Value
nil
Documentation
If non-nil, spell-check only words that were edited.
By default, this is nil, and Flyspell checks every word across which you move point, even if you haven't edited the word. Customizing this option to a non-nil value will not flag mis-spelled words across which you move point without editing them.
This variable was added, or its default value changed, in Emacs 30.1.
Probably introduced at or before Emacs version 30.1.
