Customizing The Keyboard; The Prg/Modes/Keys Sub-Menu - HP 50g User Manual

Customizing the keyboard

Each key in the keyboard can be identified by two numbers representing their
row and column. For example, the VAR key (J) is located in row 3 of
column 1, and will be referred to as key 31. Now, since each key has up to ten
functions associated with it, each function is specified by decimal digits
between 0 and 1, according to the following specifications:
.0 or 1, unshifted key
.2, key combined with „
.3, key combined with ‚
.4, key combined with ~
.5, key combined with ~„
.6, key combined with ~‚
Thus, the VAR function will be referred to as key 31.0 or 31.1, while the UPDIR
function will be key 31.2, the COPY function will be key 31.3, the upper-case J
is key 31.4, and lower case j is key 31.5. (Key 31.6 is not defined). In
general, a key will be described by the arrangement XY.Z, where X = row
number, Y = column number, Z = shifting.
We can combine a given key with the USER key (left-shift associated with the
~ key, or „Ì) to create a customized key action. In principle, the entire
keyboard can be re-defined to perform a number of customized operations.

The PRG/MODES/KEYS sub-menu

Commands useful in customizing the keyboard are provided by the KEYS menu
accessible through the PRG menu („°). Setting system flag 117 to SOFT
menu, the sequence „ °L @) M ODES @) K EYS
produces the following KEYS soft menu:
0.01 or 0.11, not applicable
.21, key simultaneous with „
.31, key simultaneous with ‚
.41, key combined with ~
.51, ~ key simultaneous with „
.61, ~ key simultaneous with ‚
