Typed END, MID, CEN, GCEN, NOD, QUA, INT, APP, EXT, INS, PER, TAN, NEA,
PAR (any start of the word from three letters, with `_`/`'` prefixes)
and NON push a one-pick snap frame on the point-modifier layer: the
prompt reads "Endpoint of:", a typed point is snapped with that mode
alone within the aperture (or rejected with "No Endpoint found for
specified point."), and the canvas snaps the cursor with it
(Session::snap_override). A command's own keyword still wins (ARC/ZOOM
`cen`); `_cen` always snaps. Overrides nest with FROM and the filters.
Shift+right-click or Ctrl+right-click on the canvas opens the object
snap menu (From, Mid Between 2 Points, Point Filters, the snap modes,
None, Osnap Settings...), whose items type the same overrides. Tab over
a snap marker with nothing typed cycles the candidate snaps
(pointmod::snap_candidates: the running snap first, then the closest of
each mode).
