Connection point
A connection point is the location where MusiCAD knows that an object connects to. At a connection point you may alter the properties of the corresponding object.
Connection-points are used for text, symbols and lines and are visible as small blue triangles during edit.
Note that notes, automatic bar lines and embellishments like tr do not have any connection point.
Clef, key and meter, rehearsal signs explicit (hard) bar lines and text all have one connection point, whereas crescendo and legato bows have two.
