I know Sean just suggested 2.4.3, but 2.4.3 is about focus order (tab key) and starts with " If a Web page can be navigated sequentially ...", which your page ist obviously not. 
2.1.1 says it must be accessible by keyboard (tab key or other browser function). If you need a mouse to activate the button, then 2.1.1 fails (although I am ignoring the num block on the keyboard, which kann also control the mouse. It is not a too practical solution, though). On not too practical terms 2.1.1 is really hard to fail.
To test keyboard accessibility you shouldn't have a screen reader running. At least if you are testing by WCAG.
