What does the arrow do?

Explanation of the arrow button in the Memory Clean window that controls whether the window is docked or undocked.

The arrow in the top-right corner of the Memory Clean window controls whether the window is docked or undocked.

  • Arrow pointing up -- The window is undocked. You can move it freely around your screen by clicking and dragging the title bar.
  • Arrow pointing down -- The window is docked to the menu bar icon. It will appear and disappear when you click the menu bar icon, similar to a dropdown panel.

Click the arrow to toggle between docked and undocked modes.
