Many times I have been asked how to change the result window from Text to Grid and vice versa. There are three different ways to do it.
Method 1 : Key-Board Short Cut
Results to Text – CTRL + T
Results to Grid – CTRL + D
Results to File – CTRL + SHIFT + F
Method 2 : Using Toolbar
Method 3 : Using Menubar
