I read this description of a different example, substitute command and it was very helpful, but I'm still not fully certain how to interpret the commands in :g /start1/.,/start2/-1 move /end/-1. It is supposed to be something that has the text start1 on some line, followed by text, followed by a line that contains start2, followed by a line that has end. In outline, like this:

texttexttext .Rh start1 .Rf some text some more ... .Rh start2 more text ... .Rh end textytextytext 

The search-and-replace command is supposed to take everything from .Rh start1 to just before .Rh start2 and move it between .Rh end and textytextytext.

The way I read it so far, :g /start1/... says to globally search for start1 and do .... Now since the ... is .,/start2/-1 move /end/-1 what does this mean? I take the . to be a regex for "any character", which is just followed by a comma. Is Vim searching for that character-comma combination? Or is it replacing the start1 line with it?
