Multiple global shortcuts for the same action

In KDE4, I want to be able to change my sound volume both with the built-in Volume Up key as well as Meta+U.

While I can define alternate keybindings for all program-wide actions, there is no such column in the Global System Shortcuts settings. How can I define multiple global keyboard shortcuts for the same action?


You might look into a program like AutoKey. https://code.google.com/p/autokey/
