Show all applications using keyboard shortcut Problem:

Show all installed applications in the /Applications folder using keyboard shortcut.

Desired solution:

Potential utility/tool that runs in the background to show all applications upon keyboard shotcut. I know there has been a software that does this but do not remember the name.

Any suggestions?
As I understand the question, the shortcut is built-in to OSX:


Switch to Finder (clicking on the desktop is quick)
cmd+shift+A


This brings up the Applications folder in the Finder. (Or were you asking for something else?)
