Check if there is a keyboard input (not a specified key input)

Question

Since Input.anyKey indicates mouse input as well, and Input.inputString only contains visiable characters, I can't find out the way to check whether there is a keyboard input correctly except for checking KeyCode one by one.
So what's the correct way to do so?

 // Press A
 if(Input.GetKeyDown(KeyCode.A)){
 }

 // Press A always
 if(Input.GetKey(KeyCode.A)){
 }

 // Don't press A anymore
 if(Input.GetKeyUp(KeyCode.A)){
 }

This is what "checking $$anonymous$$eyCode one by one"... And I have to test hundreds of keys just like that... So there isn't any better idea?

O$$anonymous$$, I know what you mean. Use this.

 public void OnGUI()
 {
     if (Input.any$$anonymous$$eyDown)
     {
         Event e = Event.current;
         if (e.is$$anonymous$$ey)
         {
             Debug.Log("Current $$anonymous$$ey is : " + e.keyCode.ToString());
         }
     }
 }

This isn't what was asked for and this is exactly what I am looking out for too. Any key pressed on the keyboard should be detected. Input.anyKey includes mouse click unfortunately.

LeeroyLin just specifies the keycode here

I have worked on a work around, looked into the docs https://docs.unity3d.com/ScriptReference/$$anonymous$$eyCode.html

 if(!Input.Get$$anonymous$$eyDown($$anonymous$$eyCode.$$anonymous$$ouse0) 
             && !Input.Get$$anonymous$$eyDown($$anonymous$$eyCode.$$anonymous$$ouse1)
             && !Input.Get$$anonymous$$eyDown($$anonymous$$eyCode.$$anonymous$$ouse2)
             && !Input.Get$$anonymous$$eyDown($$anonymous$$eyCode.$$anonymous$$ouse3)
             && !Input.Get$$anonymous$$eyDown($$anonymous$$eyCode.$$anonymous$$ouse4)
             && !Input.Get$$anonymous$$eyDown($$anonymous$$eyCode.$$anonymous$$ouse5)
             && !Input.Get$$anonymous$$eyDown($$anonymous$$eyCode.$$anonymous$$ouse6))
         {
             if (Input.any$$anonymous$$eyDown)
             {
                 Debug.Log("<color=red> $$anonymous$$ey board key pressed</color>");
             }
         }

Hope it helps somebody, if anyone got a better way to do this please do update this

I tried to use the anonymous thing, but it didn't work, and the link you psoted is broken. I suspect that Unity has since deprecated this functionality.

See my earlier reply to you under the other answer. This page has got corrupted, ignore all the anonymous nonsense - they're all just supposed to be 'K'!

it seems that the comments are lost, which is exactly the answer. look at this: https://docs.unity3d.com/ScriptReference/Event.html And then I shall get Event.current.keyCode in OnGUI, and do whatever I would.

Event has an is$$anonymous$$ey property, not used it myself but it sounds like it might help
