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 ~, 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 , 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 @)MODES @)KEYS produces the following KEYS soft menu: The functions available are: Page 20-5
