commandPressed

commandPressed is a JavaScript function designed to detect and handle modifier key presses, specifically the Command key (⌘) on macOS and Ctrl key (Ctrl) on Windows and Linux. It acts as a utility to simplify the process of checking if a specific modifier key is held down during a keyboard event.

The primary use case for commandPressed is within event listeners, such as those attached to mouse clicks or other keyboard events. By calling commandPressed, developers can ascertain whether the Command or Ctrl key was active at the time of the event. This is particularly useful for implementing custom shortcuts or differentiating user actions based on modifier key usage.

Typically, commandPressed would be implemented to return a boolean value. This value would be true if the Command or Ctrl key was pressed and false otherwise. The function likely achieves this by examining the `metaKey` property of the keyboard event object, which is standard across most modern browsers. The `metaKey` property is typically true when the Command key (on Mac) or the Windows key (on Windows) is pressed. For cross-platform compatibility, the function often also checks the `ctrlKey` property, which is true when the Control key is pressed.

The library or snippet providing commandPressed may offer additional functionality, such as detecting combinations of modifier keys or allowing developers to specify which modifier key to check for. However, its core purpose remains the simplified detection of the Command/Ctrl modifier.
