shortcut

A shortcut is a path, method, or algorithm that reduces the time, effort, or distance required to achieve a result compared with the standard or expected route.

Physical shortcuts are alternate routes that shorten travel distance or time, often found in urban areas, trails, or building layouts. They may be unofficial or temporary, and can carry safety or legal considerations, such as restricted access or hazards.

In computing, a shortcut refers to a quicker way to perform an action. Keyboard shortcuts are key combinations that trigger commands (for example, Ctrl+C to copy, Ctrl+S to save, Ctrl+V to paste; on macOS, Cmd+C, Cmd+S, Cmd+V). Desktop shortcuts, such as Windows .lnk files or Mac aliases, are links that launch programs or open documents. Shortcuts can also be command-line or scripting techniques that simplify repetitive tasks.

In problem solving and mathematics, shortcuts or heuristics provide approximate or faster methods to reach a solution when exact methods are difficult or time-consuming. While convenient, they may reduce accuracy or reliability in some cases.

Etymology: the term derives from the idea of a path shorter than the usual route; used in English since the early modern period. The concept has broad applicability across domains, from everyday navigation to software usability and analytical reasoning.
