Hide application from menu and show when we want to
<p>I want to hide my app from main menu, when user want to, s/he can see their app.</p>

<p>To hide the app I've removed the launcher category, and for now the app get hidden but now I don't understand how can the user launch the app. I've read somewhere that using a key combination (on the DialerPad) one can show the main screen of activity. How is this done?
Any other ideas of launcher an app when a launcher is not present? </p>
