Functions

bindHotkeysToSpec

Signature	hs.spoons.bindHotkeysToSpec(def, map) -> none
Type	Function
Description	Map a number of hotkeys according to a definition table
Parameters	def - table containing name-to-function definitions for the hotkeys supported by the Spoon. Each key is a hotkey name, and its value must be a function that will be called when the hotkey is invoked. map - table containing name-to-hotkey definitions and an optional message to be displayed via hs.alert() when the hotkey has been triggered, as supported by bindHotkeys in the Spoon API. Not all the entries in def must be bound, but if any keys in map don't have a definition, an error will be produced.
Returns	None
