SF bug #833957: Ctrl+key combos stop working in IDLE

Make key combinations work with upper and lowercase as is the MS standard.

Lib/idlelib/config-keys.def

 # IDLE reads several config files to determine user preferences.  This
 # file is the default config file for idle key binding settings.
 # Where multiple keys are specified for an action: if they are separated
-# by a space (eg. action=<key1> <key2>) then the keys are altenatives, if
+# by a space (eg. action=<key1> <key2>) then the keys are alternatives, if
 # there is no space (eg. action=<key1><key2>) then the keys comprise a
 # single 'emacs style' multi-keystoke binding. The tk event specifier 'Key'
 # is used in all cases, for consistency in auto key conflict checking in the
 # configuration gui.
