The Kee4 keyboard functionality, including lowercase, uppercase, numeric and special characters
and control codes for cursor positioning and editing,
is available to any device supporting the Bluetooth HID protocol without the need for any drivers or
additional software (support for some of the control codes may vary on specific devices).
To take advantage of possible program-specific and/or programmable codes
and function keys, additional software designed for specific devices may be installed.
When using the Simulator, some keyboards have problems with reporting the key down
events when more than two keys are pressed at the same time (before one of them is released).
This does not affect the composite keystrokes, but the Reset
keystroke (which is performed by pressing three of the four characters at the same time)
may produce wrong results.
If this happens while using the simulator on your keyboard, use the numeric pad keys (if available)
instead of the keys v, b, n and m.
If you must use the v, b, n, m keys, try pressing 'bnm' instead of 'vbn'.
If that does not work, you can also use a separate key just for the Reset functionality;
you may use one of the following: z, x, c or the space bar.
The current design provides for two Alternate modes.
The exact mapping and supported functionality for these modes is to be determined.
The characters/codes generated by these modes are expected to support additional or program specific
functionality.
On advanced models of the Kee4 device the Alternate modes might even be user definable
- i.e. the user could change the mapping of the keystrokes in these modes
to provide key-codes specific for his or her preferred device.
The Alternate modes are not supported by the Simulator.
The Control mode lock works slightly differently - it affects only the cursor positioning characters (generated by the simple and rolling keystrokes). The characters generated by the rocking keystrokes are NOT locked. A different set of special characters is generated in the Ctrl Lock mode, but the keyboard returns to the previous mode after the character is typed. Refer to the complete character map to see the characters and control codes generated in the Ctrl and Ctrl Lock modes.
For example the character 'j' is typed by a rocking composite keystroke from key 1 to key 4 and back:
For example the character 'w' is typed by a rolling composite keystroke from key 1 to key 4:
For example the keystroke 2-3 indicates a rolling composite keystroke, performed by a 'rolling' motion of the hand from key 2 to key 3:
The keystroke 2=3 indicates a rocking composite keystroke, performed by a 'rocking' motion of the hand from key 2 to key 3 and back to key 2:
