As an experienced computer user, I find the following rather ridiculous
For example, if you want to launch Firefox, you can press the Windows key, start typing the word Firefox, and press Enter when the Firefox shortcut appears. It’s a quick way to launch programs, open files, and locate Control Panel options without even touching your mouse and without digging through a cluttered Start menu.
Either the writer of this article has some sort of mouse allergy or he totally doesn't realize that (a) most people have desktop icons as shortcuts (b) simply double click on the icon opens the program.
So simple and absolutely no need to bother with the Windows key as he suggests.
