Browsers

Paste functionality

For some browsers, like Chrome, you need to enable pasting for a certain webpage. Pasting is used, to easily move your program from your favourite editor into the sandbox environment.

In Chrome you can find this under Settings / Privacy / Site Settings, there you can see if you managed to disallow using clipboard for your site.

Audio

Audio only works on webpages after a user click. B3 waits with audio initialization until the first key pres event has been noticed. This has been tested to work on Firefox and Chrome.
