2/ already shares another meaning in many other places.
1/ When touch typing, is easier than :
With both hands resting on the keyboard, :
left thumb => Alt
right pinkie => Enter
On the other hand,
- forces your left hand to travel to the top function row,
- force your eyes to watch your hand (with a laptop keyboard, the
function keys are not separated)
- force your left hand to travel back to the middle row,
to be ready to type the class name.
