Famulus provides you with a simple portable app and file launching utility.

Famulus operates a little differently than other launchers by utilizing a specific set of typed commands instead of a polished UI. This fact is intended to keep this launcher simple and as light as possible on your system's resources. The way Famulus works is by briefly pressing and holding down the Numpad's * key. This action brings up a prompt in which you can type a variety of predefined commands for your files and folders. Famulus also allows you to directly run typed web addresses, system commands, and specific file paths by prepending a search with the @ symbol.

Included in the zip file for Famulus is a PDF file that contains all the relevant commands that can be used.
