xfce4-xkb-plugin

Written by Alexander Iliev, this plugin allows you to setup and use multiple (currently up to 4 due to X11 protocol limitation) keyboard layouts.

You can choose the keyboard model, what key combination to use to switch between the layouts, the actual keyboard layouts, the way in which the current layout is being displayed (country flag image or text) and the layout policy, which is whether to store the layout globally (for all windows), per application or per window.

If a certain flag is missing, the plugin will fallback to displaying the layout as text.

The plugin detects any change in the layout configuration (e.g. setxkbmap invocations) and reconfigures itself to use the new settings.

NOTE: Lots of code was borrowed from the XfKC project by Gauvain Pocentek.
