I had been havng troubles with editing large programs. My machine sometimes doesn't do the tool change quick enough or sometimes the power blinks. So I would have to edit these large programs to remove what has already run in order to start from where it was at. I had never known how to select code and drag the slider to the top of the program to select all of this quickly.
Today I figured it out. Just start highlighting the code, hold down the shift key and then drag the slider to the top of the program.
I can't tell you haw many time I spent several minutes, wiggling, my mouse at the top of the screen to get it to scroll up the program faster.
I feel pretty silly now though for never having tried this before. Maybe I can save someone else some trouble in the future.
