Launchy

System - program Starters

New
Launchy: indexes the programs in your start menu and can launch your documents, project files, folders, and bookmarks with just a few keystrokes! When you run Launchy, it is completely hidden. You activate it by pressing [Alt-Space], and dismiss it by pressing [Esc]. Enter the first few letters of a file or program, and Launchy automatically displays the rest of the name. You simply press [Enter] to open or launch it.

You can find the instructions for portability on my website.
