You dont, what you do is go to Operator menu then down to Edit Button Scripts, your buttons will flash, clcik on one and then put the appropriate code in it then exit, do the same again for the next button and you are done.
You only need to place macros in the macro folder if you wish to use from within your code, if you want to do that then you will have to name them similar to M101.m1s and M102.m1s then when you called those m codes from code your tailstock would work.
