Q:

clusterssh: some key combinations are not passed to terminals

Normally when I have my text editor open in terminal, I use the key combination CTRL+K+V to move to the end of the file
CTRL+K+V does not work when I am in the "main cssh input field", (ie when i am typing in multiple terminals). But if I select one of the open terminals directly, then CTRL+K+V works.
So I assume, when I use it in the main input field, it gets "eaten".
Ideally, I would like cssh to pass all key combination to the terminals.
I don't need cssh to use its own key shortcuts.
Is there somewhere where I can configure / disable key shortcuts used by cssh, so that all are passed to terminals ?
Another problem is, when I press F10, it is not passed to the terminals, but opens the menu of cssh. This is pure evil. The cssh window already has menu, where I can click with mouse and select items. Who needs to sacrifice F10, for such stupid thing?
Is it possible to disable all keys in cssh, so that all are passed to the terminals ?

A:

If I unserstood it correctly you want to disable all shorctus for the cssh.  This could be done by disabling it in the configuration file.
In your /etc/csshrc & $HOME/.csshrc you need to configure it to:
   use_hotkeys = no
       Setting to anything other than "yes" will disable all hotkeys.

The source of the information were the FreeBSD man pages for cssh
Edit - adding more options
You can try to leave these options empty - don't assign it any default key combination:
   key_addhost = Control-plus
       Default key sequence to open AddHost menu.  See below notes on
       shortcuts.

   key_clientname = Alt-n
       Default key sequence to send cssh client names to client.  See
       below notes on shortcuts.

   key_paste = Control-v
       Default key sequence to paste text into the console window.
       See below notes on shortcuts.

   key_quit = Control-q
       Default key sequence to quit the program (will terminate all
       open windows).  See below notes on shortcuts.

   key_retilehosts = Alt-r
       Default key sequence to retile host windows.  See below notes
       on shortcuts.

   mouse_paste = Button-2 (middle mouse button)
       Default key sequence to paste text into the console window us-
       ing the mouse.  See below notes on shortcuts.

Edit - for future readers  The issue appeared to be in the GUI env itself - which was OpenBox.  You need to watch out if the settings of the environment do not colide with the cssh ones.
