Never forget a Photoshop or Lightroom shortcut again
Even longtime Photoshop and Lightroom users sometimes forget the myriad of keyboard shortcuts used to trigger the program’s powerful features. For newcomers it’s even harder to remember (or even realize) more obscure actions like Alt-F9, which shows or hides the Action pane in Photoshop (did you know that? We didn't) or that Command-Shift-B sets a target catalog in Lightroom.
If you also consider the different keystrokes which are only available in different modules or modes, and a user can experience what we like to call 'Keyboard Overload Syndrome'.
Previously the only treatment for this condition was by purchasing color-coded stickers to overlay on top of a keyboard as a reminder of its function, but now web developer Waldo Bronchart has made a web application called 'Application Shortcut Manager'. It's an interactive website that displays all the keyboard shortcuts for Photoshop, Lightroom and Blender - including the shortcuts for all the modes and modules.
The site is a great training tool and photographers with dual monitors can even keep it open on one display while working in another. The app has keyboard setups for Mac OS X, Windows and Linux operating systems.
As an open source project hosted on GitHub, the application will grow over time as more developers contribute to it. Try it out and let us know what you think in the comments.
