Have you ever wanted to use a Lightroom or Photoshop shortcut you heard or read about but you don't remember what the shortcut was? I keep forgetting Lightroom's shortcuts all the time (especially those I don't use too often). I've run across a website with interactive Adobe Lightroom and Photoshop shortcuts that makes finding the shortcut you're looking for really easy - Application Shortcut Mapper (click here).
Application Shortcut Mapper has currently shortcuts for 3 applications: Adobe Lightroom, Adobe Photoshop and Blender. If I'm not mistaken, the latter one is an open source 3D rendering application.
