This key performs the same function as pressing "Space-e (dots 1-5)."

"Space-z (dots 1-3-5-6)."
You can use combinations of the function keys to allow you to do many
tasks. Pressing "F1" and "F2" at the same time will work the same as
"page up" on a personal computer. If you press the "F3" and "F4" keys at

explained in greater detail in the section 2.10, entitled, "Multi-Tasking."
