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 ?
