-- you should use this sparingly.
-- A call to this function will remove all bindings previously set with this
-- function. For example, set_key_bindings({}) would remove all script defined
-- key bindings.
-- Note: the bindings are not active by default. Use enable_key_bindings().
--
-- list is an array of key bindings, where each entry is an array as follow:
-- {key, callback}
-- {key, callback, callback_down}
-- key is the key string as used in input.conf, like "ctrl+a"
-- callback is a Lua function that is called when the key binding is used.
-- callback_down can be given too, and is called when a mouse button is pressed
-- if the key is a mouse button. (The normal callback will be for mouse button
-- down.)
--
-- callback can be a string too, in which case the following will be added like
-- an input.conf line: key .. " " .. callback
-- (And callback_down is ignored.)
