FvwmKb is a module for Fvwm and Scwm window managers that makes it more comfortable to work with several Xkb keyboard layouts. For the focused window it stores the currently locked Xkb group (keyboard layout) in its internal database and restores it when the window is focused again making an impression that different windows simultaneousely have different selected keyboard layouts. It tells the window manager to reflect the currently locked Xkb group in the window decoration making it possible to tell which windows have which locked groups easily.
