Hey, thanks for the great guide. I'm somewhat new to modifying this and need some help. What I'd like to do is create a new tab (which I can do) and use some buttons for specific symbols (such as the summation symbol or tickmarks). I know how to get the buttons on, but how do I get it to link a button to insert a specific symbol? Is it possible to do this just using xml code or do I have to use macros? I'd like to set this up on multiple computers to work with all spreadsheets, but I know word or excel don't have macros enabled automatically and if I can avoid using macros I'd prefer that. Thanks again!
