First turn your keyboard 90 degrees counter clockwise! Then select your layout (most likely QWERTY I think).

Now imagine your hand is a little guy or spider that wants to climb from the 1st, bottom row ("1,Q,A,Z" on a QWERTY layout) to the 9th row ("9,O,L,Period"). To climb you'll have to hold on to the keys you've already reached and try out the keys higher up to get a grip on them.
