ESP8266: #include <Keyboard.h> causes fatal error: HID.h: No such file or directory
The Keyboard library is for Arduino ATMega32U4 based Arduinos (and other similar ones with USB) only. The ESP8266 does not have USB, so how can it possibly use the Keyboard library?

Will an Arduino Nano work instead of Teensy 3.2?
No, you can't use Adruino Nano, because in this project the Teensy board has been used as an USB Keayboard and Nano has separate communication chip (FTDI or CH430) that can't emulate USB keyboard.
