I wonder why all my books on Microsoft Office never pointed this out and it took How-to Geek to show us this neat trick in Word 2007 – selecting text vertically. This is pretty useful when editing lists. I’m not really sure if “vertical” is the right term for this feature since it actually allows you to click and drag diagonally to make the selection.
All you have to do is to press and hold down the Alt key then clicking and dragging over the selection.
You can use this not just for lists but it’s pretty hard to do with paragraphs since words are necessarily of the same length and alignment for you to be able to do it neatly.
