This might be a bit neurotic, but it's driving me nuts. I can't seem to get these lines perfectly straight and after modifying all kinds of canvas settings, I'm out of ideas. Arrow up looks like the picture I've attached, arrow down causes it drop below the line, creating a kink in the other direction. Any help appreciated!
Select both tools, then right-click and choose Align Horizontally.
Choose one tool and press the arrow in the appropriate direction to get the line dead straight 🙂
NOT neurotic, just OCD like me
