Keyboard Launchpad (KLP) is a program that allows you to quickly and easily assign hot keys to launch programs, visit URLs, paste saved clipboards, control individual programs, perform system commands, and more.
What makes KLP special is that it works system wide. No matter what program you're in, no matter what you're doing, you can always access the hotkeys of KLP. It also has an open plugin format so that if there is a specialized program you wish to add your own hot key support to, you can do so.
