CmdPlusMinus

CmdPlusMinus is a widely used term describing a pair of keyboard shortcuts on macOS that combine the Command (Cmd) key with the plus or minus key to adjust on-screen scale. In common practice, Cmd++ and Cmd+- trigger zoom in and zoom out actions, affecting either the entire user interface or the content area of the active application. The shortcuts are supported across many programs, including web browsers, word processors, image viewers, and development environments. A related shortcut, Cmd+0, is frequently provided to reset the zoom level to the default.

Key details and variations: On standard US keyboards, the plus sign is entered by Shift plus the equals key, so the practical instruction is often described as Command plus equals for zoom in and Command plus minus for zoom out. Some applications may require different key interpretations or offer alternative bindings, and in certain contexts the reset command may be Cmd+0 or another customizable option. The general concept of CmdPlusMinus, however, remains consistent: it is a quick method to adjust content size without navigating menus.

Usage and scope: CmdPlusMinus is particularly valued for accessibility and productivity, allowing users to scale text and graphics to suit readability or display preferences. While most desktop applications implement these shortcuts, the exact behavior can vary: in browsers, zooming may affect the entire page; in editors or IDEs, it may adjust font or canvas scaling.
