I don’t know if you’re familiar with this issue, but when you’re selecting at the end of long lines, it’s very easy to move the mouse up or down and make it select the whole line, like it jumps. And then I have to repeat the process again, either being extra careful or using keyboard instead.
Here’s a video to show what I’m saying: https://dl.dropboxusercontent.com/s/34wvtueeemlgb7d/2018-11-08_02-11-23.mp4
Is there a setting to avoid this?
