The command to create latex commands can operate in three modes. If the keyword arguments is given, add arguments from the "arguments" section in the ini file is inserted between the curly braces following the command. If the keyword "that" is given, the command will select the last utterance using "select that" and use this as an argument to the command. A typical use is "emphasise that". Finally, if the keyword "line" is given, the command will use the contents of the line as an argument to the command. A typical use of this functionality is "section line" which makes the current line into a section heading.
The "label" keyword to this command will cause an appropriate label to be added on the next line after the command itself. This is only applicable for the commands that also are listed in the "label" section of the ini file, in all other cases the "label" keyword will be ignored.
