1:
Wrap by Window.
“Select Line” or “Select Logical Line”.
Move cursor left/right/up/(down).
** The selection could extends 1 (more) view line downward.
This issue will be fixed on the next version v18.7.0.
2:
“Select Line” or “Select Logical Line” 3 times.
** It’s in multiple-selection mode.
Just like F8 (Select Character), EmEditor allows you to select multiple lines. If you “select Line” 2 times, and then press Up or Down to go to another line and “Select Line” to select 2 lines.
