There are lots of nano-gnomes in my keyboard. They are always dodging this way and that, tumbling upside down, getting mashed by quickly depressed keys, but still they manage to change much of what I type. It is a never-ending story…that of trying to quash the pesky rascals. They must not have been hungry or they would have left supper where it belonged instead of making it super. 

They do those things just to hear my explicative and expletive command of language — where else do you think gnomes learn their troublesome magic spells. They only times I have ever found them helpful is thusly:

1. They have an uncanny knack of infecting keyboards of typists and writers. This makes a great means of sabotage or revenge. It is very simple, just hold down the Cntr-Alt keys and every so softly whisper the URL of your target. In a blur you’ll see a blue streak whirl through the keys and blast into the Internet dragging bits and pieces of verbal flotsam and keyboard jetsum. Vouched, warranted, guaranteed. You’betcha’
2. Or, if you are studying the history and magic of gnomes you will find that they make less havoc in your results. It doesn’t seem to matter much to them which variety of gnome you are writing about being that they are a very close-knit species. However, there is a miniscule improvement if you are specifically reporting on nano-gnomes.

In the softest tones you can whisper in, if you speak of dropping snack cake crumbs, or tiny bits of fresh chocolate chip cookies, fibers from your clothes such as threads and lint, flakes of dead skin, hair, and nail clippings, they will calm down in anticipation of these edible or usable rewards. Mostly though, they can’t hear the human voice as it is like the roar of a storm gale. This leaves us severely handicapped in our struggle for normalcy on the keyboard.
In closing, I should remind you to frequently clean your keyboard with a high-powered vacuum cleaner running at full power. There is no need to toss the debris into the nearest blender set on puree for they will immediately escape once you turn off the vacuum. No, your only defense is to leave the vacuum running, attached to a very long extension cord, and toss it into the ocean. Not the river, the lake, or the nearest pond. It has to be an ocean because only passing seahorses are attracted to nano-gnomes escaping from a drowning vacuum cleaner. 
Remember to buy stock in your favorite vacuum cleaner manufacturer and carry insurance on runaway drowning vacuums. It will save you a lot of headaches. Oh, and never mention within a mile of a keyboard how you disposed of your vacuum.
