Key code translation bug in src/tty.zig

In **src/tty.zig** function _eventFromRecord(...)_:

```
354: const base_layout: u16 = switch (event.wVirtualKeyCode) {
...
411: 0x76 => Key.f8,
412: 0x77 => Key.f8,
...
}
```


Probably at line **411** should be _Key.f7_.

Also didn't see an asterisk _'*'_ in the symbol list starting at line **447**.
