Handy VS2003 tip
When working with a very long line of code, have you ever wanted to select a part of the string with your mouse, but by accident the cursor moves into the line above. Then all of the sudden the whole previous line is selected and the screen scrolls over to the end of the line above.
Very annoying, yes?
Here's a nice way to prevent that from happening - hit <Alt> while you are selecting. This puts you into block selection mode so no scrolling occurs.
