I am planning a screencast and would prefer to use PuTTY from my Windows 7 (x64) box. However, I want the audience to see what keys I am pressing on screen.
For Linux there are screenkey or key-mon, but what can I use on Windows? I don't care if it is shareware, but FLOSS would still be preferred.
NB: this is not about the best program, it is asking for any such program as I haven't been able to find one even after putting considerable effort into the search. This is also not about software to record the screen contents in any way.
Meanwhile I also found KeyJedi, but the program won't show just any key presses. It only shows particular ones (e.g. with Alt and Ctrl) so it doesn't solve the problem.
