Page 14: Key Mapping
Handheld Scientific, Inc. 5. Key Mapping Key mapping is such an important feature that it deserves its own section in this manual. With key mapping, every keyboard becomes programmable. The possibility is unlimited. For instance, you can set up a keypad as a media control center by mapping the keys to volume up, down, stop, play, etc. -
Page 15: Advanced Mappings
Handheld Scientific, Inc. 5.2 Advanced Mappings Advanced mappings are the ones where the source key is a compound key such as alt+f1 or ctrl+alt+s. Since they have to be searched and matched for each key stroke, there could be performance penalty. Therefore, the number of advanced mappings is limited to 16 and they should be used judiciously. -
Page 16: Key Mapping Examples
Handheld Scientific, Inc. 5.4 Key Mapping Examples This section shows key mapping examples. Keep in mind that you need to execute the “save” command for any changes to survive re-starts. // swap the left alt and com keys, to use a Windows keyboard with a Mac, or vice versa... - Page 17 Handheld Scientific, Inc. // 0xc000223 is the keycode for “Home”.

Handheld Scientific, Inc. 6. Advanced Features This section describes other useful features such as macros, timers and layers. 6.1 Macros A macro is a series of keystrokes or mouse movements (or mix of them). It can be used in many places where key names are expected. -
Page 19: Timers
Handheld Scientific, Inc. 6.2 Timers Timers are used to send out keystrokes or mouse movements periodically. They are useful in preventing connections (wired or wireless) from timing out, or the host from entering into sleep due to inactivity, hence this feature was previously called “keep alive”. You can setup up to 4 timers. -
Page 20: Layer
Handheld Scientific, Inc. 6.4 Layer A layer is a group of settings (mappings, macros, timers, etc.) that can be switched together easily. It provides a way to completely change the layout or functions of a keyboard with a simple shortcut. There are 4 layers (1-4) in this version of the firmware. When you are using the keyboard or in command mode, you are always working on a specific layer. -
