+ * \var lyx::kb_action lyx::LFUN_CALL
+ * \li Action: Executes a command defined in a .def file.
+ * \li Notion: The definitions are by default read from lib/commands/default.def.\n
+ A .def file allows to define a command with \\define "<NAME>" "<LFUN>"
+ where <NAME> is the name of the new command and <LFUN> is the lfun code
+ to be executed (see e.g. #LFUN_COMMAND_SEQUENCE).
+ \\def_file "FileName" allows to include another .def file. \n
+ This is particularly useful in connection with toolbar buttons:
+ Since the name of the button image for this lfun is
+ lib/images/commands/<NAME>.png this is the way to assign an image
+ to a complex command-sequence.
+ * \li Syntax: call <NAME>
+ * \li Params: <NAME>: Name of the command that must be called.
+ * \li Origin: broider, 2 Oct 2007
