DID YOU KNOW: 20 of the #pico8 typeable symbols are predefined fillp() patterns! Pass each one as the argument—without quotes—to get a fill pattern that looks a bit like the symbol.
The remaining 6 typeable symbols are the “button” symbols: Shift+U for up, S+D for down, S+L for left, S+R for right, S+O and S+X for the O and X buttons. These are defined to be used as arguments to btn() and btnp().
