I searched and thought for sure I would find something but alas, no.  In the past (2010?) I had no problem RMB and getting the quick snap option to select a tangent (quadrant) on an arc or an intersection, etc.  But for some reason now it does not show up when I right click.  I have the QS toolbar up top and figured that would be easier but that seems useless.  I have turned my snap option off and on.  I really cannot figure this out.  What am I missing??
