Hello,
If it's the dollar symbol, it is present on the AZERTY keyboard, usually on the right side.
You can also obtain it with the key combination Alt + 36 (type the numbers on the numeric keypad).
If this is not what you want, reply by attaching a drawing of what you desire.
What is well conceived is clearly expressed,
And the words to say it come easily.

Actually, it's the letter that I've circled in red that I can't manage to do.
It's the dollar symbol used on Mac keyboards. I don't know how to recover it for Windows.
