odd error

I am honestly a bit lost as to why keys.append() is not a good choice
here, but I have it working. I apparently have to use the ascii for
capital letters if I am capturing the shift modifier, not the
lowercase ascii. Using 67 instead of 99 works as expected.

I use append because the program has three different modes.
Eventually, each mode may have its own keystrokes. When the user
switches modes, the previous mode's keystrokes are unregistered and
the new keystrokes, keys[currentModeNumber], are registered. The same
with the functions; when a function is called from the dictionary, it
is called using funcs[currentModeNumber]. Again, this lets me put all
my functions into one big list, where each member of the list is a
dictionary. I probably have the terminology wrong, but hopefully that
makes sense. Sorry for not explaining that earlier, but I was just
looking for problems in the key codes. Thanks for your help!
