Use this command to slave the scales of the windows listed in the window list (wlist) to that of the master. For example if you use
MM 1 X 3 4 7
Then every time you change the X scale in window 1 then the X scales of windows 3, 4 and 7 will also be updated to be the same as what is in window 1. Any attempt to change the X scale of windows 3, 4, and 7 for example using a "R X4" type command, will be ignored.
