如何在Eclipse中从方法实现跳转至接口的方法定义（Ctrl+T反向操作）

Hey there! I totally get wanting to quickly jump from a concrete method implementation back to the interface method it’s overriding or implementing—this is exactly the reverse of using Ctrl+T (Quick Type Hierarchy) to explore type hierarchies. Here are the easiest, most straightforward ways to do this:

• Quickest keyboard shortcut: F3 (Open Declaration)
  Place your cursor anywhere inside the method implementation (name, body, even the parentheses), hit F3, and Eclipse will immediately jump to the corresponding interface method definition. If your class implements multiple interfaces with a method of the same signature, a small selection window will pop up letting you pick which interface’s method you want to view.

• Mouse-friendly alternative: Ctrl+Click (Cmd+Click on Mac)
  Hold Ctrl (or Cmd on macOS) and click directly on the method name. This does the exact same thing as F3—takes you straight to the interface definition, with a selection prompt if there are multiple matching methods across different interfaces.

• Right-click menu option
  If you prefer using the mouse without shortcuts, right-click on the method name, hover over the Navigate submenu, and select Open Declaration. You’ll land right at the interface method definition just like the shortcut methods.

Just to clarify the difference from Ctrl+T: Ctrl+T shows you the full type hierarchy (all parent classes and implemented interfaces) for the current class, while these methods take you directly to the specific interface method that your concrete method is implementing—super handy when you need to quickly check the original method’s Javadoc or signature!
