Hello, To type a set in mathed, {a,b}, my first movement was to use the bracket keys, the same way I use the parenthesis when I don't need a too beautiful delimiter. However the brackets are displayed in red and, bad surprise, are not in the output.
I see the point to link the brackets to some 'red text' after you type a command, but not in the middle of the formula. Is there a justification to this behaviour ? In the meantime, I will rewrite all my brackets... Adrien Rebollo --
