bugfix for keys
- initialize count, so that there is no initial keypress at powerup
- use int8_t instead of uint32_t to pass new key, since only 1 new key

attempt to reduce space usage
- remove unecessary code
- ifdef "extra" code
- pass data through globals instead of functions accessing static data
