How the keyboard system works

• 2 main files
• gui-readline.c
• keyboard.c

structures are:

• KEYBOARD_REC
• KEYINFO_REC
  • id, description, list of keys and default keys.
• KEY_REC
  • ptr to KEYINFO, key (str), data (str)

keyboard.c

• init() initialises the keys/defaultkeys hashes

• key_bind() takes id (multi, command, nothing, ...), desc, default, data, and callback

• it checks if the id already exists in keyinfos, otherwise creates and adds it.

• it adds a signal 'key $id", with the callback as handler.

• emits keyinfo created.

• if it already has a keyinfo, it adds it to both default_keys and keys maps.
