   get_context_mapping() at the bottom of the file is called by action.c as usual.
   if the context is for the remote control its then passed straight to
   target_get_context_mapping().
   These tables are only used for the touchscreen buttons, so at the end of each
   CONTEXT_CUSTOM2 is OR'ed with the context and then sent to target_get_context_mapping()
   (NOTE: CONTEXT_CUSTOM2 will be stripped before being sent to make it easier.)
   In the target keymap, remember to |CONTEXT_CUSTOM2 in the  LAST_ITEM_IN_LIST__NEXTLIST() macro
   to speed it up a tiny bit... if you dont it will go through these tables first before going
   back to the target file.
