I’m looking for an option to not allow the cursor to go to the previous line when the cursor is at the beginning of the line and I hit the left arrow key. Is there such an option?
In v9.06, if you select some lines of text and select “Narrowing”, then the behavior becomes what you described. This is actually a bug, and will be fixed in future versions. However, I might add the same feature in the future versions as an option. Thanks!
