selecting vertex from dope sheet

When viewing key frames in the dope sheet, is it possible to select vertices or objects in 3D view by selecting their keyframe?

The reason i ask this is because when using the Anim all addon ive run into instances where earlier keyframes are disrupted because i seem to have added vertices possibly from accidental extrude or subdivide, or maybe they werent keyframing initially? I’m really not sure though because i thought anim all automatically keys every vertex on an object and i dont think i added any points.

Basically i see a bunch points in the dope sheet where vertices only have keys after halfway through the animation and i would like to be able to select all those keyframes in the dopesheet and see the same vertices selected in the 3D view so i can edit or delete them.
