Avoid showing hidden applications in the cmd+tab navigation menu I recently switched to OS X Mountain Lion. I have applications like Skype and Pidgin which start at login and are hidden, but when I have more applications running and I do ⌘ cmd + ⇥ Tab to switch between application these hidden applications also appear there.

How can I avoid showing them?
Here is a blog post from someone who managed to remove Finder from the Application Switcher by adding this entry:

 &lt;key&gt;NSUIElement&lt;/key&gt;
  &lt;string&gt;1&lt;/string&gt;


To the info.plist file of the specific app (in this case, Finder).
