Motorola MT2000 用户手册

Every action of the RSS is controlled by you through the use of formatted displays and function keys. The
function keys are the ten keys labeled F1 to F10 grouped on the left hand side of the keyboard, but be aware that
some other keyboards may have twelve keys labeled F1 to F12 across the top of the keyboard.

F1  - Displays help information on every screen and menu. This on-line help provides
information on how to use the currently displayed menu, screen, line or field. You may
also find system setup information. In many cases the help provided is for the specific
line currently highlighted on the screen.

F2 - F9 - The F2 through F9 keys perform special functions and actions which can vary
from menu to menu and screen to screen. 

On some screens, F5 will print the current

screen to your printer, and F8 will save the data and options currently displayed.

F10 - Exit to previous menu or screen. The F10 key moves the display backward in the
RSS tree, one screen or menu at a time. F10 performs this function on 

every menu and

screen. At the MAIN MENU, F10 exits the RSS program.

Esc - Exit to MAIN MENU. Esc performs this function on every menu and screen.

Tab - Accepts data currently in a field then moves the prompt forward one field. If entry is
not accepted, an error beep will sound. This key performs exactly like the Enter or
Return key.

Enter or Return - Accepts data currently in a field then moves the prompt forward one
field. If the entry is not accepted, an error beep will sound. This key is usually two or four
times as large as the letter keys on the keyboard. This key performs exactly like the Tab
key.
