Description:

The xxkb program shows the current keyboard layout (an XKB group) and
allows to switch it with a mouse click. It has some additional features.
The xxkb remebers the layout for each application window and changes
the keyboard state accordingly when the window gets a focus. The xxkb
can place an additional button on a window titlebar and that button is
a switcher and an indicator for that separate window. If the keyboard
map has more than two layouts the xxkb can simplify a switching using a
two_state mode. In this mode the xxkb allows to choose two layouts, one
as a base layout and another one as an alternative layout and then switch
the keyboard state between them only. Also the xxkb supports applications
lists which allow to tune its behavior for some separate applications.

The xxkb works with any window manager.
