It can be useful to see the list of active keys for a given context.  This
 idea was partially motivated by changeset #7689, which put a comment into
 tv_play.cpp with the list of allocated keys, although I ran into this
 problem when customizing my own keybindings.

 Anyway, mythcontrols lets you see ACTION => KEY mapping.  This patch lets
 you see KEY => ACTION mapping for a given context.  It presumes that key
 mappings go through one context, and then default to "global" context.
 Any key resolved in non-global context does not fall-through.  This it not
 necessarily representate true behavior, and definitely wrong if you
 consider jump point bindings.

 It can be useful in any case.

 To use this, go into 'Edit Keys', select a context and press the "MENU" or
 "INFO" key.  This pops-up a dialog with the option "Used Keys".  This will
 create a similarly-looking list that lists all the keys, one per item.
 The mapping is displayed like "I => INFO".  If there are multiple options,
 the are comma-separated.

 The keys are displayed in sorted order: first the digits, then the
 characters, then unmodified keys, then modified keys (of any sort).
 Within each category, the keys are sorted alphabetically (thus, Ctrl+F10
 will appear before Ctrl+F9).

 The display is currently purely informative: you cannot edit anything in
 this display (yet).
