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.
Depending on the species of mayfly, the adult may only live long enough to transform from pupil stage, eat food, breed and then die. Sometimes, they do not even live long enough to eat for long. When a group of mayflies get together, predators like birds, spiders and other insects get together for a real feast.
