====== Your Twiddler 4 Journey Begins Here ======

The Twiddler 4 is a fully functional keyboard, mouse, and nano-capacity USB storage device.  It operates in both a wired and wireless mode.  In the wired mode, the Twiddler is attached to a host device via a USB-C cable.  The USB cable supports both communications from device to Twiddler as well as charging the Twiddler.  In the wireless mode, both keyboard and mouse commands are sent to the host device through Bluetooth (BLE 4.2).

The Twiddler 4 is also a chordic input device. You use the Twiddler with one hand and press one or multiple keys at a time, called key chords, to generate keystrokes.  Key Chords are like playing chords on a piano or guitar.  From the factory, each key on a standard keyboard is mapped to a particular chord.  Pressing a certain key chord will cause the Twiddler to send that key stroke to the host.  

All chords are remappable and customizable and can also be more than one character long.  While one key chord could send out the letter “a” another key chord could be mapped to type out your entire email address.  With proper mapping of common prefixes, words, phrases and suffixes a substantial increase in typing speed can be realized.

The Twiddler 4's newest feature is the Optical Finger Navigation (OFN) Touchpad that works as a mouse to help you navigate your pointer. Just slide your thumb over the touchpad in the direction you would like the mouse to move. Pressing down on the Touchpad will create a mouse click event. The Touchpad can operate in two modes:  Mouse and Scroll Wheel.
