Keyboard security

I was recently testing a software system of a sensitive nature to the extent that the developers had disabled the ctrl-key, alt-key as well as the two shift keys. All was going well until I had to enter a password with uppercase letters. With everything locked down how would you enter the uppercase characters. I recalled a similar system I had test in the past, where the interface was mouse only. In this case, I used the Windows charmap to draft an email character by character. Today, I used charmap once again to enter the uppercase letters and login to the system and do what I had to do. I could understand the need for security but disabling the ctrl, alt and shift keys I thought was going a little to far.
