Documentation

Do the appropriate preview thing at point.

If point is positioned on or inside of an unmodified preview area, its visibility is toggled.

If not, the surroundings are run through preview. The surroundings don't extend into unmodified previews or past contiguous previews invalidated by modifications.

Overriding any other action, if a region is active (transient-mark-mode(var)/transient-mark-mode(fun)), it is run through preview-region.
