Push button as "channel changer" ?

Hi I am new to this thing called coding on Arduinos and I am asking for some help
I have these LEDs WS2812 they foprm a 13x18 grid on plexi glass which is going inside a helmet. My dream idea is I start out with a smiley face then when I click the button on my bread board it changes the " channel" so to speak to a cool pattern or scrolling text. I would love up to 10 channels. any help would be much loved. I am working on a arduino nano fwiw

Search for some example code to store and output patterns (channels) to the LEDs, and how to read and debounce buttons. All that has been discussed and done already. Come back when you have specific questions.
