I do not remember what the application to display a list of applications in the style of "Camera Lens Launcher. "

Someone hung the application and can not remember who or what is called the application.

Does anyone know what it is and where to download it?

Did you allow select applications from the external keyboard?

Thanks.

I use the "App Search" widget. You click on it and it shows a list of all installed apps. You can then scroll the list or use the keyboard to search incrementally.

Have a look here: http://talk.maemo.org/showthread.php?t=59010

As root from xterm:

dpkg -l

If you want to search the list, type:

dpkg -l | grep -i <app name>
