How to switch keyboard layout with Alt-Shift in OpenBox?
xkb is correctly configured using dpkg-reconfigure.
Didn't give any advice.
When working with GNOME, everything works fine, no tweaks.
When working with KDE, switching works by Ctrl-Space, it cannot be configured.
When working with XFCE, switching works with Ctrl-Space, it can be configured to work with Alt-Shift.
What am I doing wrong?
