Use the Size command to size a window. After choosing Size, you can resize the window with either the arrow keys or the mouse. The shortcut key is CTRL+F8. If you use a mouse, the window will shrink or grow as you move the mouse or as you drag the size box in the lower-right corner of the window. The new size is highlighted as you shrink or expand the window. Press ENTER when the window is the desired size, or press ESC to cancel sizing.
