If I have a sketch open and I try to highlight a few lines, I click the start location and drag the mouse down, and the highlighting flies down way too fast overshooting where I want to stop before I have a chance to stop it. Is there any way to slow this down?
Change your mouse pointer speed? You should try it with rolling a finger on a laptop touch pad. You learn to make sloooooow movements!
This mod slows that down: http://forum.arduino.cc/index.php?topic=118440.0 (but it is v1.0.5 not v1.5.x)
