Editting Character Sheets via Macro?

Is it possible to create a macro that would edit a players gold without having to open a character sheet? I'm having trouble finding any answers on this, But, I was hoping for something similar to this [[@{Character Sheets|gold}-?{Cost}]] This only gives me the value of what it would become, but I was hoping to find a way to make the result replace the character sheets current gold value. Is this possible?

AFAIK, no. Character sheets are read-only in regards to macros.

This is possible via the API only, not via macros.

Mallind, as a mentor, you can use the API for that, and the API can be actuated by a macro.

So, could the API be used to apply a temp condition or buff? It would be cool to click Rage-On or Rage-Off macros and have the character sheet "adjusted" accordingly. Is there currently a script floating around here that could be used for this?

You definitely could do that in the API. There are some scripts around that would let you change attributes, and if you knew how you needed to change them and how to change them back, you could write macros that would do that. You could definitely write a script that understood the mechanics and handled it all more automatically.
