Function Key
Descriptions
The following are the function keys of the terminal’s keypad.
Cancel Key
Pressing the cancel key in normal mode—when the terminal’s application is
loaded and running—usually has the same effect as pressing the Esc (escape)
key on a PC. That is, it terminates the current function or operation.
In terminal manager, use cancel to perform a variety of functions. The most
common use of cancel in terminal manager is to exit a terminal manager submenu
and return to the main Verix Terminal Manager menu. The specific effect of
pressing the cancel key depends on the currently active terminal manager menu.
Backspace Key
In normal mode, the backspace key is commonly used to delete a number, letter,
or symbol on the terminal’s display screen. Press backspace one time to delete
the last character typed on a line. To delete additional characters, moving from
right-to-left, press backspace once for each character or hold down backspace to
delete all characters in a line.
In Verix Terminal Manager, the specific effect of pressing the backspace key
depends on the currently active terminal manager menu.
ALPHA Key
In normal mode, the ALPHA key enables you to enter one of the two or more
characters or symbols assigned to individual keys on the 12-key Telco-style
keypad (note that this is in normal mode and is application-specific).
The terminal manager functions described in the Entering Verix Terminal
Manager section requires you to enter numbers, letters, or symbols using the
keypad.
The terminal’s operating mode and context determine the specific action
performed when you press one of the function keys. The following descriptions
are provided solely to acquaint you with some general characteristics of these
function keys before presenting more detailed terminal manager procedure
descriptions.
