Can I call by key code? Because I don't know the specific key name

[xiaoxiaohuayu]

Is your feature request related to a problem? Please describe.
My program can only use the keyboard, but my keyboard is customized, only code does not have a specific key name, for example, the key code is 9999

Describe the solution you'd like
Go through the code to make the call

  keystrokes.bindKey(9999,()=>{
    console.log('9999')
  })

Describe alternatives you've considered
Right now I don't have a good alternative.
Although it is possible to alias by setGlobalKeystrokesOptions, it is still based on the key name.

setGlobalKeystrokesOptions({
  keyRemap: {
    '9999':'spacebar'
  }
})
