Description

When i write "\left\lbrace" in math mode, it's concealed as "[".
But i would like to have instead "{".
I've read the part of the documentatin talking about that and tried to change this behaviour.
I managed to get "{" with "\lbrace" but don't know what to do with the whole "\left\lbrace".
Is that possible to override the default behaviour ?
