As I understand when we program the Arduino as a keyboard the HID works not by sending ASCII codes but by sending the physical location of the key, based on a US Layout. I, however, have a different layout and would like to send a keypress of the left uppermost key, the key on the left of number '1'. I have tried sending:
Keyboard.press('`');
Keyboard.press('"');
Keyboard.press('§');
but none of them seem to work. Any suggestions ?
