I am guessing the wavy line from one chord up to another chord is called "double mordent," from my looking online. How it is played?
Definition of DOUBLE MORDENT
a melodic ornamentation consisting of four grace notes or tones preceding a principal note or tone and executed by a rapid alternation of a principal tone with its lower auxiliary tone
The important point appears to be the playing of the grace notes as fast as possible
In the case of both mordent and double-mordent the tones are sounded as quickly as possible, the time taken by the embellishment being subtracted from the value of the principal note as printed.
