You are probably thinking of the grub command savedefault. That is a grub internal command. I checked the grub documentation in the info utility and this is the closest that I came to what you asked.
The menu file is named menu.lst, not menu.1st.
There is a grub utility that you run from the Linux command line called grub-install. Maybe that is what you meant.
In my experience the savedefault command doesn't work. I always have to edit the menu.lst file to change the default entry. When you edit the menu.lst file you don't have to do anything else. The grub-install program is just for putting the grub boot code onto the MBR.
