Use VoiceOver to move and resize items on Mac
Move and resize windows and some objects in apps, such as graphics and text boxes.
Note: VO represents the VoiceOver modifier. See Use the VoiceOver modifier.
Move
Navigate to the item you want to move, then press either VO-` (for a window) or VO-Command-` (for an object).
VoiceOver tells you if an item can’t be moved.
Move the window or object in one of these ways:
Up, down, left, or right: Press the arrow keys.
Diagonally: Press the VO modifier with the Up Arrow or Down Arrow key and the Left Arrow or Right Arrow key. For example, to move a window diagonally toward the upper-right corner, press VO-Right Arrow-Up Arrow.
To stop moving the window or object, press the Escape key or Fn-Tab.
You can’t use other VoiceOver commands until you stop moving the item.
You can use certain number keys to quickly move windows and objects around the screen: the top (left, middle, and right) section using keys 1, 2, and 3; the center (left, middle, and right) section using keys 4, 5, and 6; and the bottom (left, middle, and right) section using keys 7, 8, and 9.
Resize
Navigate to the item you want to resize and press either VO-~ (for a window) or VO-Command-~ (for an object).
VoiceOver tells you if an item can’t be resized.
In the Resize menu that appears, choose Resize, Resize and Move to Grid, or Resize and Move to Section.
Navigate to the submenu where you can choose to resize an edge or corner, resize and move to an area of a grid such as the top left, or resize and move to a section, such as the bottom half.
Resize the item.
Resize an edge: Use the VO and arrow keys (for example, press VO-Right Arrow to extend the right edge of a window or object).
Resize a corner or handle: Use the VO and two arrow keys (for example, press VO-Right Arrow-Up Arrow to extend the top-right corner of a window or the top-right handle of an object).
To stop resizing the window or object, press the Escape key or Fn-Tab.
You can’t use other VoiceOver commands until you stop resizing.
