Operating System Shortcuts
Operating system shortcuts sit underneath every other application on this site, and they're arguably the highest-leverage shortcuts to learn precisely because they apply constantly regardless of which specific program you happen to have open — window snapping, virtual desktop switching, and screenshot capture are used dozens of times a day by nearly everyone, in a way that even the deepest application-specific shortcut set can't match for sheer frequency.
Windows
Snap-based window management, virtual desktops (Task View), and File Explorer navigation, the daily-driver shortcuts for the majority of desktop users worldwide.
macOS
Mission Control, Spaces, Spotlight, and Finder shortcuts built around Apple's distinct window and virtual-desktop management philosophy.
Windows Terminal
Modern tabbed terminal application for Windows, with pane-splitting and profile-switching shortcuts beyond a legacy single-window console.
PowerShell
Windows' scripting shell and command-line environment, with history search and tab-completion shortcuts for faster command entry.
Raycast
Mac-only Spotlight replacement and extensible launcher, with clipboard history and window management layered on top of core app search.

CleanShot X
Mac-only screenshot and screen-recording utility popular with designers and developers for its annotation tools and scrolling capture.
Linux (GNOME Desktop)
The GNOME desktop environment used by default on Ubuntu and Fedora, with window management and Activities Overview shortcuts distinct from Windows and macOS.
Linux (KDE Plasma)
The KDE Plasma desktop environment used by default on Kubuntu and Fedora KDE Spin, offering a more Windows-familiar window management model than GNOME.

Because OS-level shortcuts apply globally rather than being scoped to one application, they're also the ones most likely to conflict with an application's own shortcut for the same key combination — worth keeping in mind when a shortcut that should work inside a specific app instead triggers a system-level action, which usually means the OS has claimed that combination first before the application ever sees the keypress. This category also covers the everyday system utilities layered on top of the base OS — file managers and launchers, screenshot tools, password managers, archivers, remote-desktop clients, and virtualization software — since all of them are used constantly across every other application rather than being tied to any one workflow, the same reasoning that puts Windows and macOS themselves at the top of this list.
