TextField not clear after focusing it through a Key

Question

Greetings unity community,

I have a chat field that is represented by a GUI.Window and a TextField at the bottom of that window.

 function OnGUI() {
     window = GUI.Window(1, window, GlobalChatWindow, "Chat");
 }
 
 function GlobalChatWindow(id : int) {
    /*here be actual chat window logic etc, not really important as it works*/
 
     //sets the control name
     GUI.SetNextControlName("chatField");
 
         //creates an actual field
     inputField = GUILayout.TextField(inputField);
 
         //getting focus when pressing the 'T' button    
     if (Input.GetKeyDown(KeyCode.T)) {        
         GUI.FocusControl ("chatField");    
     }
 }

The problem hereby is, that the inputField takes on the 't' string and I can't seem to delete that t as the logic records it when I'm out of the if logic already.

Say the TextField is unfocused and I'm running around ingame. Then I press 'T'. The field gets focused but with the content 't' which I have to delete manually afterwards.

How do I get rid of this? inputField = ""; either doesn't work at all (when inside the if logic) or too good and blocks all chatting when outside the if logic.

Greetings, Cirrus

Here is an alternate solution. I cannot say it is better:

 function OnGUI() {
      var e = Event.current;    
      
     window = GUI.Window(1, window, GlobalChatWindow, "Chat");
 
         //getting focus when pressing the 'T' button 
     if (e.type == EventType.KeyUp && e.keyCode == KeyCode.T && GUI.GetNameOfFocusedControl() != "chatField") {   
         inputField = "";
         GUI.FocusControl ("chatField"); 
         focused = true;
     }
 }
  
 function GlobalChatWindow(id : int) {
  /*here be actual chat window logic etc, not really important as it works*/
     GUI.SetNextControlName("chatField"); 
     //creates an actual field
     var st = GUILayout.TextField(inputField);
     // Don't save the string if we don't have focus
     if (GUI.GetNameOfFocusedControl() == "chatField")
         inputField = st;   
 }

Here is a bit cleaner solution. I hesitate to include it since I don't know if there are any implications to rewriting the character in the event. Maybe someone with inner knowledge of Unity can comment:

 function OnGUI() {
      var e = Event.current;    
      
     //getting focus when pressing the 'T' button 
     if (e.type == EventType.KeyUp && e.keyCode == KeyCode.T && GUI.GetNameOfFocusedControl() != "chatField") {   
         inputField = "";
         GUI.FocusControl ("chatField"); 
         focused = true;
         e.character = 0;
     }
     window = GUI.Window(1, window, GlobalChatWindow, "Chat");
 }
  
 function GlobalChatWindow(id : int) {
  /*here be actual chat window logic etc, not really important as it works*/
     GUI.SetNextControlName("chatField"); 
     //creates an actual field
     inputField = GUILayout.TextField(inputField); 
 }
