Locate line when 'end on' in ortho view..best way?

a 1 pixel yellow spot is tricky amidst other lines, which seem to want to attract my snap.
What is the best way of selecting the end of a line when requirements dictate I need to get hold of it in a view at its end.

I usually draw another line from its end then use that, but if I go to the ortho view of it end on, and choose zoom selected, it should appear in centre of view, but its still virtually undetectable.


I guess you could skew the view temporarily (CtrlShift RMB drag) then UndoView after the selection.
