I pushed Roger's patch so that the Windows section of config-keys.def is in a consistent state. However, this does not fix the problem for config-extensions.def or user versions of config-keys.def. A) The basic method of the key dialog does not allow entry of proper pairs. B) it is easy to forget to enter both versions when using the advanced method or editing a file directly.

So rather than develop a similar patch for the Unix block, which is always missing the uppercase version of key-bindings, our GSOC student will work on code to add the 'other' version when alpha key-bindings are read. If and when that works, the Unix block will work as is and the Windows block can have removed what will then become duplicates.
