Then we use the `process_record_user` function, which is called whenever a key is pressed or released, to check if our custom keycode has been activated.
If yes, we send the string `"QMK is the best thing ever!"` to the computer via the `SEND_STRING` macro (this is a C preprocessor macro, not to be confused with QMK macros). If yes, we send the string `"QMK is the best thing ever!"` to the computer via the `SEND_STRING` macro (this is a C preprocessor macro, not to be confused with QMK macros).
We return `false` to indicate to the caller that the key press we just processed need not be processed any further. We return `true` to indicate to the caller that the key press we just processed should continue to be processed as normal (as we didn't replace or alter the functionality).
Finally, we define the keymap so that the first button activates our macro and the second button is just an escape button. Finally, we define the keymap so that the first button activates our macro and the second button is just an escape button.

This defines two macros which will be run when the key they are assigned to is pressed. If instead you'd like them to run when the key is released you can change the if statement: This defines two macros which will be run when the key they are assigned to is pressed.
