This is a little tip that will help you move around text. It works in AutoCAD and Word and I even tested while in my blog text editor and it works. If you would like to move your cursor to switch to the beginning of the next word, simply:
Hold down CTRL and use the LEFT or RIGHT arrow buttons.

To jump to the bottom or top of the paragraph:
Hold down CTRL and use the UP or DOWN button.

(The cursor in the below picture may be hard to see – sorry)
