windows 7 x64 - Where do you write VBA code in Visio 2013 -

there lot of tutorials automating visio via vba, none of them address where code supposed go. example, in excel, can right click worksheet tab , select option "view code". open text editor window , can insert code there.

is there such text/code editor visio? if not, add vba code visio?

in microsoft office productivity tool alt+f11 open vba code editor. create or open file , hit alt+f11. don't have visio 2013 works in 2010.
