Not really:

This is the result for keys pressed in a cmd.exe:

If Ctrl-f is pressed (Ctrl key is originally Caps Lock),
then you simply get an uppercase F (like when pressed

If Caps Lock is pressed once (Caps Lock key is originally
Ctrl key), then all following keys are interpreted as
escaped letters (like when pressed with Ctrl normally):

* press Caps Lock once
* type f -> get ^F
* type g -> get ^G
* press Caps Lock once again to undo this behaviour

Note: There is also a registry hack under windows to swap
the Ctrl and Caps Lock keys which does makes things even
more confusing though.
