2.2 KEY DATA
The <data> to be assigned to the selected chord can
be in one of four formats.
1. A Predefined Key
2. A Text String
3. A Make/Break Scan Code Sequence
4. A Combination of Predefined Keys
Regardless of the format used, the Twiddler2 will auto-
matically parse the string entered, and if valid, will
respond with an OK message. If an error exists, the
Twiddler2 will display ERROR. When the available
memory is not sufficient to store the new entry, the
Twiddler2 will display the following ...
Insufficient Memory
0009 Bytes Available
Note that when editing the key map, mouse key, and/or
constants, the Twiddler2 stores the changes temporarliy
in a previously unused portion of the memory. This
allows the user to abort the Program Mode without sav-
ing the changes. However, this temporary storage
mechanism also requires substantial overhead data. As
such, if the memory becomes full, simply exit and re-
enter the program mode. This will commit the changes
and remove the overhead data freeing up additional
memory for more changes.

typed, will cause the Twiddler2 to issue a the corre-
sponding thumb/finger combination for that key followed
by an equals sign. At this point the user only needs to
type the <data> field to be assigned to the key.
The Auto Chord feature is enabled/disabled by pressing
the CTRL key. Upon entry into the programming mode,
the Auto Key feature is disabled. Pressing the CTRL
key will enable this mode as indicated by the Twiddler2
displaying the following message ...
Auto Chord Active
To disable the Auto Key function, press CTRL again
and the Twiddler2 will respond with ...
Auto Chord Disabled
Note that the state of the Auto Chord feature can only
be altered when no data has been typed on a line, i.e.
the cursor must be at the beginning of a line. With the
Auto Chord Active, pressing the key labeled
A
will
cause the Twiddler2 to type the following ...
0 R000 =
and the user can now assign a new function to this
chord.
