32-code Key Panel

a minimal 26+2 key alphanumerpunctrol entry keyboard

[See also: the 16-key ZooMath Glorified Adding Machine do-all RPN calculator, advanced optimal calculatory keypanel scheme; also one-button remote control]

The 26 letters, a-z, are necessary and sufficient for a keyboard in English: Double-detented deep-press invokes shift and capitalization; Numbers and punctuations, also deep-pressable, are the key-defaults; Thumb-keys enable words and controls (interpreted as punctuational controls, more suitably than acronymic controls, to control actions: eg. arrows that go, numbers that go-to); And 4 more non-key codes, for deep-pressed, key-released, code-reference, null, finish the 32 codes.

Words are automatically spaced by the enable-word thumb-key; Controls are automatically null-separate by the enable-control thumb-key. 26 more controls can exist by deep-pressing keys; But the 5 sets of 26, less 10 digits reduplicated, plus 4-8 non-key controls, fill a 128-count 7-bit block: A 6th set is not defined.

Alternation between words, punctuations, controls, and numerics, does not invoke automatic spacing/nulls - until the thumb-key is redoubled. However, deep-pressing the thumb-word-space, tabs, and deep-pressing the thumb-control-null, escapes. [There's room for a third thumb-key]

The finger-keys, thumb-keys, and non-key device-codes, at 150 baud, are quick enough for real-time 4-finger chordal music generation.

The keys are laid out symmetric for either single-hand easily fingered reach: 4-6 rows with keys assigned converging about upper-middle-palm,--

--,taxonomically represent the English arrangement of similar phonemes, and exercise the fingers along 2-3 axes.

2×16 punctuations are suggested arranged around the 10 digits in the center: left-directing punctuations located on the left, separators above and below, right-directing on the right: and related stronger punctuations by deep-pressing: An arrangement is suggested (above).

Single-handed entry enables accountability while the other hand holds books, rovots, manual controls. Reduplication of the thumb-keys on opposite sides of the keyboard arrangement extends the keyboard to bi-handed actuation: Thumb-left or thumb-right activates the finger keys symmetrically laid for right-hand or left-hand utilization.
