Documentation

Toggle marks: marked files become unmarked, and vice versa.

Flagged files (indicated with flags such as C and D, not with *) are not affected, and . and .. are never toggled. As always, hidden subdirs are not affected.

In Transient Mark mode, if the mark is active, operate on the contents of the region if dired-mark-region is non-nil. Otherwise, operate on the whole buffer.
