[openbox] Citrix Thin Client Project - Focus Issues

It is not completely clear for me but I think your issue is to send
"alt+tab" keys to Windows because for now when you type "alt+tab" the keys
are used by OpenBox, switching between your Citrix client window and other
windows hosted on Linux side.

If I'm right, you just have to tell OpenBox to ignore "alt+tab", so the
keys won't be grabbed by OpenBox and will be thrown to the active window,
which could be your client. Then perhaps this client will be able to send
the keys to the remote system, which in turn should switch its own

To do that, have a look into your ~/.local/openbox/rc.xml file and look for
something similar to that :
    <!-- Keybindings for window switching -->
    <keybind key="A-Tab">
      <action name="NextWindow"/>
    <keybind key="A-S-Tab">
      <action name="PreviousWindow"/>

It's an extract from my own rc.xml, A-Tab = Alt+Tab in rc.xml syntax.
Change that to something else :)

Then to push that system wide rather than only for your own account I think
it's in /etc/xdg/openbox directory you'll have to push that modification.
This should confirmed, I'm not sure ;)
