snaping on a bezier curve


how to snap cursor to edit point on a bezier curve - in my case if i select editpoint -> move cursor to selection - the cursor moves in the middle of the control handels - why that ?

thanx a bunch

uuhh… i forgot one - i joined 2 beziercurves now how can i merge end/startpoint to get one curve
so in the manual it says f - it works fine but not in my case, i must have messed up the order of the initial curve - is there a way to flip start/ end of a curve ?

big greets - thanx
