Once you have a good handle on the Home keys, you can start expanding to the other keys on the keyboard. Use the same repetition exercises to memorize the locations of the other keys. Use the nearest finger to reach the key. If you are keeping your wrists elevated, you will be able to easily strike the keys that are slightly outside of your reach. 6
Image credit Life Cycle of Aquatic Insects, USEPA. Gilbert Rowley illustrates the mayfly life cycle from the egg to the nymph and through the various adult stages (emerger, dun and spinner) that are of interest to flyfishers.
Incomplete Metamorphosis has three stages: Egg, Nymph, and Adult. Insects that go through three stages of change in their life cycle have an incomplete metamorphosis while complete metamorphsis has four stages. The first stage of incomplete metamorphisis is the egg. During this time, the insect will hatch into a form called a nymph.
