General information on MT9750 Programmable keys (P keys)

2.3 Programmable keys (P keys)

With MT9750, you can assign long or frequently used keyboard input to function

keys. These keys are then referred to as “Programmable keys (P keys)”. Pres-

sing a programmable key has the same effect as inputting the corresponding

characters and keys directly using the keyboard. Using the P keys, you can

save commands that have to be entered repeatedly in the same form and call

them any number of times.

A maximum of 20 P keys (P1 to P2) can be assigned under MT9750. The P keys

are mapped to the PC keyboard function keys; thus, the key is mapped to

the function key on the standard PC keyboard for example. You can also

operate the programmable keys using a separate Function Keys window. This

window is accessed under Settings: Keyboard Mappings: Function Keys Window.

If you are uncertain about the mapping of 9750 function keys (such as P keys)

to your PC keyboard keys, you can check the mapping under Settings: Keyboard

Mappings: Keyboard Mappings (see also “Keyboard mappings“).

Programmable keys are defined session by session, i.e. they are valid for the

session in which they were defined. There are two utilities available for assi-

gning the P keys: one for recording programmable keys during input and one

for editing programmable keys regardless of the data entry in the session win-

dow.

The programmable keys’ assignment can also be changed by the host applica-

tion (e.g. by the PLUS program).

2.3.1 User-specific P keys

In addition to the P keys with which you may be familiar from the original device,

MT9750 contains another memory area for storing P key assignments which

cannot be overwritten by host applications. It is thus possible to work with host

applications that modify the P key assignments, and at the same time go back

to the individual key mapping.

The user-specific P keys are mapped in the same way as the normal P keys

using the P key editor, but in this case as the “Px’ key.
