How to show keyboard input coming to ssh-server from ssh-client?

Question

I'm running ssh-client (from git package) on Windows and connecting to Ubuntu 11.x ssh-server.

Strange, but ShiftFx keys fails. When I press ShiftF7 Byobu proceed the action as ShiftF5 and so on.

Is there a way to understans where is the bug? Can I run some tool in remote console to view typed keys? Sort of KeyEvents do for Windows?
