Custom HID: Mini Editing Keyboard

** Introduction ** This is an Arduino Pro Micro-driven custom mini-keyboard prototype for editing text when using a smartphone or tablet.

The code/keys are for arrows, shift+left/right arrows (to select text), home, select all, copy/paste, undo/redo, and delete. But you can redesign and recode the keyboard to do anything you want using Arduino's Keyboard Modifiers guide: https://www.arduino.cc/en/Reference/KeyboardModifiers

It is just a prototype. We want to gather some user experience and see where to go from here.

** Parts **

* (13) mini-push button switches (4 pins, 2.5mm tall button);
* (2) M3 x 15mm bolts and nuts;
* (2) M3 x 10mm bolts and nuts;
* (1) Arduino Pro Micro;
* (1) Perfboard cut to 46x79mm;
* (1) USB-micro-USB cable with OTG adapter;

Your OTG adapter depends on whatever device you want to use your keyboard for. If you're using it for a desktop for some reason, the USB cable itself is adequate. Some phones use micro-USB and others use Type-C adap
