So, I was working on a live keyboard for my makeyOS v4, and for a very long time, I couldn’t get the backspace to work. The way I was testing it made me not notice the arcade machine resetting. Basically, the backspace key, when using the browser event extension, cannot be used because it resets the game. Is there a way to unlink it or fix this issue? Thank you

You’ll need to disable the system keys (or at least disable the _Menu_ system key). I don’t think there’s a block version of this yet, but here is the code in JavaScript:
```typescript
keymap.setSystemKeys(0, 0, 0, 0)
```
