This is so true. The basic error the article makes is equating number of keys typed with efficiency. Not all key presses are equal. When you navigate with letter searches you have to think much more than holding down an arrow key until you're at the point you want to be, or even better moving your mouse pointer. Fingers are quick, brains are slow. Especially when you are already using that brain at full capacity for the programming task itself. I for one welcome touch screens for programming, which are even better than a mouse (touch screens are of course not a good replacement for a keyboard, they are however a good replacement for a mouse for many tasks).
