Init commit with many years of arduino sketches and projects. I dont know if the esp8266 includes much, but there are also libraries. I hope they dont have crazy automatic versioning through the Arduino IDE.

|| @description
|
||||
|| | This library provides a simple interface for using matrix
|
||||
|| | keypads. It supports multiple keypresses while maintaining
|
||||
|| | backwards compatibility with the old single key library.
|
||||
|| | It also supports user selectable pins and definable keymaps.
