RWMA (Ruby window manager addons) is a modular system for adding various keyboard driven actions to (usualy minimalistic) window managers, inspired by ruby-wmii. Its main purpose is launching programs and displaying notifications but can be expanded with plugins (for example translation, music player control, volume control).
