the keyboard layout colemak shifts the keys around into a different location than they would be on a traditional qwerty keyboard. however, if you're typing with the colemak layout on but you press the keys in the location they would be in a qwerty layout, you end up with a bunch of gibberish. this tool just lets you decipher (and create) whatever colemak-qwerty gibberish you want.
you can even convert it several times and use it as a simple cipher.
eventually, it will go in a cycle.
here are the cycle amounts:
qwerty <> colemak: 42
qwerty <> dvorak: 210
colemak <> dvorak: 24
also this only supports main keyboard stuff so if you have other symbols on your numpad that don't change, this might change it
