Parameter 1: a reference to the documents frame object.

Parameter 2: The command.

Parameter 3: Name of the target frame. In your case, this is always an 
empty string, which means that it is not specified. No problem, because 
the first parameter receives it and finds the first contained frame that 
can handle the command.

Parameter 4: Indicates how to search for the named frame. You do not 
name a frame, so, this is zero and ignored.

Parameter 5: Arguments meant for the command.

So, when you say that these stand on their own, you mean that you send 
no arguments to the command that is executed.

Because move up and move down require arguments that tell them how many. 
Note that the macro recorder does a rather poor job. One of the initial 
lead developers mentioned to me one time that he thought that it might 
have been better if it had been removed. He also mentioned roughly how 
much money and work it would take to fix.

No attempt is made to simplify the generated macro. As each step is 
recorded, a set of lines is generated. Certainly it is crude. that said, 
it works fine for many quick and dirty tasks, and then fails for others.

True and False are boolean values in basic. The "Select" argument takes 
a true or false, which you can think of as "should I select text as I 
move?" I seem to remember hearing that this was broken in LO, however, 
so you might not see any difference if you set it to true. I have not 
tested it.

I mention this above, that is for the targeted frame name if needed or 
desired. It is not specified.

Frame search options. But you did not specify the frame name.

Yes. My guess is that these values are specified here:
