    #define ID_EDIT5      105
    #define ID_EDIT6      106
    #define ID_EDIT7      107
    #define ID_EDIT8      108
    #define ID_EDIT9      109
    
    ...
    
    OnKeyDown(UINT nChar)
    {
          if(nChar == "KeyDown")FocusObject += 3;
          if(nChar == "KeyUp")FocusObject -= 3;
          if(nChar == "KeyRight")FocusObject += 1;
          if(nChar == "KeyLeft")FocusObject -= 1;

    Ah I see. My bad. Didn't know it's MFC.

    Can't help you, though. I don't know MFC.

    I use a custom Listview in report mode for this type of control.

    Or draw the text on a DC and use hot spots and mouse clicks (ie for tic tac toe).

    SetFocus() will change the focus to the required edit.

    In my example FocusEdit is a member to hold the current selected edit's ID (not offset from 101).

    Code:
    OnKeyDown(UINT nChar)
    {
          if(nChar == "KeyDown")FocusObject += 3;
          if(nChar == "KeyUp")FocusObject -= 3;
          if(nChar == "KeyRight")FocusObject += 1;
          if(nChar == "KeyLeft")FocusObject -= 1;
    
          //also needs test for invalid (?) presses ie Left Arrow in 101, 104, 107
    
           //validation for ID (please test as not checked)
          if(FocusObject>ID_EDIT9)
          {
                FocusObject=ID_EDIT1+(FocusOject-(ID_EDIT9+1));
          }
    
          //EDIT Add low value test, I am thinking switch / case instead of the 'if's
    
         // in FocusObject is for example 106 and I need set focus to ID_EDIT6
          CEdit *pEdit=NULL;
          pEdit=(CEdit*)GetDlgItem(FocusObject);
          if(pEdit)//no error
          {
                pEdit->SetFocus();
          }
          //handle error
    
    }
