Source: https://docs.rs/objc2-app-kit/latest/objc2_app_kit/struct.NSPanel.html

Call to start a drag (moving the window) in the Window Server process. In general, this can be done after a mouseDown event has come in and been examined by an application or view.

This allows the window to participate in space switching, and other system features. Pass the original mouseDown event to the method. The method will return right away, and a mouseUp may not get sent.

### contextMenuKeyDown Method

Source: https://docs.rs/objc2-app-kit/latest/objc2_app_kit/struct.NSBrowser.html

Handles a key event that should present a context menu at the user focus. This method is generally not meant to be overridden, but provides guidance on how to do so if custom behavior is required.

```rust
pub fn contextMenuKeyDown(&self, event: &NSEvent)
Available on **crate feature`NSEvent`** only.
Handle a key event that should present a context menu at the user focus.
Most applications should not override this method. Instead, you should customize the context menu displayed from a keyboard event by implementing `menuForEvent:` and `selectionAnchorRect`, or `showContextMenuForSelection:`, rather than this method.
You should only override this method when you do not want the system-provided default behavior for the context menu hotkey, either for a specific key combination, or for the hotkey in general. For example, if your application already provides a different behavior for control-Return (the default context menu hotkey definition), and you want to preserve that behavior, you should override this method to handle that specific key combination, and then return without calling `super`. Note that the user may customize the hotkey to a different key combination, so in this example, if any other key combination is passed to your method, you would call `super`.
An implementation of this method should call `[super contextMenuKeyDown:event]` to pass the request up the responder chain. If the message reaches the application object, NSApplication’s implementation of this method will send `showContextMenuForSelection:` to the responder chain. If you do not call `super`, then no further handling of the key event will be performed.
Note: In some cases, `showContextMenuForSelection:` will be called without a prior call to `contextMenuKeyDown:`. This occurs when a view receives an Accessibility ShowMenu action, or when the user has created a Cocoa Text key binding to map a different key combination to the `showContextMenuForSelection:` action.
Parameter `event`: The key down event that matches the system-wide context menu hotkey combination.
See also: `showContextMenuForSelection:`
```
