For example: 

inserting one line:
OldCaret=(x=1,y=47) NewCaret=(x=1,y=48) FirstLinePos=47 LastLinePos=48

replacing one line with one line
OldCaret=(x=1,y=48) NewCaret=(x=1,y=48) FirstLinePos=46 LastLinePos=48

replacing one line with one line
OldCaret=(x=1,y=47) NewCaret=(x=1,y=48) FirstLinePos=46 LastLinePos=48

Yes.
How to find out if synedit is in syncro mode?

How?
