where is the altgr key on a mac
AltGr key AltGr (also Alt Graph, or Right Alt[1]) is a modifier key found on some computer keyboards and is primarily used to type characters that are unusual for the locale of the keyboard layout, such as currency symbols and accented letters. On a typical, IBM-compatible PC keyboard, the AltGr key, when present, takes the place of the right-hand Alt key. In macOS, the Option key has functions similar to the AltGr key.
Shift key The keyboard symbol for the Shift key (which is called Level 2 Select key in the international standard series ISO/IEC 9995) is given in ISO/IEC 9995-7 as symbol 1, and in ISO 7000 “Graphical symbols for use on equipment” as a directional variant of the symbol ISO-7000-251. In Unicode 6.1, the character approximating this symbol best is U+21E7 upwards white arrow (⇧). This symbol is commonly used to denote the Shift key on modern keyboards (especially on non-US layouts and on the Apple Keyboard), sometimes in combination with the word “shift” or its translation in the local language. This symbol also is used in texts to denote the shift key.
