Default set - the "home" set for all kinds of typing that does not involve lots of numbers or capital letters.

default set

Complementary set (default inverse) - Contains all the standard characters not present in the Default set. To access this set from the Default set, do one of the following:
          1. For temporary access, hold down either of the Inversion keys .
          2. To get only the next character from this set, tap an Inversion key
          3. To lock the set in place, tap the Inverse set lock key (IS). To unlock the set (return to Default set),
               tap this key again.

complementary set


Numeric set - Used mainly for small-letter + numeric data processing or typing, maths operations, accountancy and telecommunications. To engage this set from any other set, tap the Numeric set lock key (NS). Tap this key again to return to the previous set. Whilst the Numeric set is engaged, using the Inversion key or Inverse set lock key as described above gives access to all the characters missing from this set.

numeric set


Caps set - Same as Default set but capitals replace small letters. Used for lengthy Caps texts, headings etc. To engage this set from any other set, tap the Caps set lock key (CS). Tap this key again to return to the previous set. Whilst the Caps set is engaged, using the Inversion key or Inverse set lock key as described above gives access to all the characters not present in this set.

caps set


Numeric/Caps set - Same as numeric set but capitals replace small letters. The most convenient locked set for doing capitalised headings etc and for many numeric tasks that do not require concurrent access to small letters. To engage this set from any other set, tap the Left Text Control key, . Tap this key again to return to the previous set. Whilst the Numeric/Caps set is engaged, using the Inversion key or Inverse set lock key as described above gives access to all the characters not present in this set.

numcaps set


Text control set - Contains a variety of cursor movements, deletes and scrolling, 12 unspecified function keys and 10 unspecified macro keys. To access this set from any other set, do one of the following:
          1. For temporary access, hold down either of the Text Control keys
          2. To lock the set in place, tap the right Text Control key. Tap this key again to return to the previous set.

Thrift keys feature

This feature allows each of the “rare” letters k, x, j, qu and z to be obtained by pressing two other keys at once, these keys being more conveniently located than the single keys allotted to those letters. The pairs of Thrift keys corresponding to each letter are as follows:
            j = gv       qu = bg       z = fc k = mw       x = cm
            q = cw
(cannot be included in swipes – see “Principal Modes”)


Dual numeric set - Enables rapid processing of voluminous numeric data with one or both hands; especially good for summing numbers and for entering data into tables; also provides an alternative numeric keypad for left-handed users. To engage this set from any other set, press NS and MS together, or hold down MS and tap the “d” key. Press again to return to the previous set.

Right- and Left-handed handed families

For use by people able to type with only the left or the right hand and willing to learn the technique for rapid typing with one hand (only feasible on a non-split keyboard fitted with some method of labelling the keys differently).

            Right-handed family Default set

right-handed default set


            Right-handed family Miscellaneous set

right-handed alternative set


            Right-handed family Caps set - same as the default set except letters are capitalised


PRINCIPAL MODES

Flick mode – the default input mode. Characters are produced by tapping the keys one after another. Except for the Thrift keys, you can’t (usefully!) hit more than one character key at once.

Swipe mode (chords) – an input mode in which two or more keys can be pressed simultaneously (“swiped”) to create small sequences of letters, numbers or punctuation signs. Typically a sequence created in this way comprises one or more consonants followed by one or more vowels. The order in which the characters appear is predetermined.

Normal mode – the default output mode used for all normal typing purposes.

Run mode – an output mode used with pre-selected proprietary software for whatever calculating and programming purposes are facilitated by the associated software. A specified programming language will be invoked and the VDU screen, or a part of it, will represent the file in which the operations are recorded.


CONTROL KEYS

A hold key is one you hold down whilst one or more other keys are tapped (like using the Shift key on a Qwerty keyboard). A hold key can also be pressed simultaneously with a tappable key (e.g. a lock key or character key); this produces the same result as tapping the tappable key whilst holding down the hold key. Some control keys are holdable and tappable. In that case, if two control keys are required to produce a certain function, you can hold down either one and tap the other, or press them both together.

Reversion

If you lock in a different set or mode by tapping a control key (or two control keys together), then tap the same key(s) again, you will revert to the set or mode you were last in. The only control key that spurns this rule is the key. This key (pressed by itself) always locks in the Default set no matter where you are or have just been!

If you hold down one of the hold keys to get temporary access to a set, when you release the key you will revert to your current working set. But note the special reversion rule when you tap the Inversion key or the VS key – see table.
