Invisible dice roll from character sheet ?

Hi, everything is in the post title, how can I gmroll from a character sheet ? I don't use my own character sheet but one of Roll20. Thank you <3

Hi, Toonsa . Character Sheets are created and managed by the Roll20 community. While there's no inherent way to choose whether or not the output of the sheet buttons on a Character Sheet is or is not whispered to the GM, some sheet authors have coded in such options. What Character Sheet are you using? It's possible that such an option exists; if not, it may be possible to ask the sheet authors or the Roll20 community to add it to the sheet.

I'm using Le dunjon de naheulbeuk (French), thank you for the answer, i thought that there was a option in the game settings "hide my rolls" or something like that, i saw the interface to create character sheet and i am not able to create or modify one. 

...you might be able to make a macro for it.  Hit the button, press the up arrow, and copy the text that appears into a macro with the "/gm" in front of it. There is also a /talktomyself command in chat that doesn't let anyone but you see what you type.  

Great, that what i was looking for :) /talktomyself , and /talktomyself to disable, i'll try to master maccro soon ! thank you for the tip, topic can be close French powaaa <3
