 Keys are mapped by first searching the keybindings for the current view, then
 the keybindings for the *generic* keymap, and last the default keybindings.
 Thus, the view keybindings override the generic keybindings which override the
 built-in keybindings.

 Keybindings at the line-entry prompt are typically governed by the readline
 library, and are configured separately in `~/.inputrc`.  See 'readline(1)'.
 Tig respects but does not require an `$if tig` section in `~/.inputrc`.
