While writing text in Hindi/Sanskrit (Devanagari script), I need a quick way to insert the Avagraha symbol(ऽ). It turns out there is an undocumented shortcut on the Mac Hindi QWERTY keyboard for that and that is shift + \

Oh and don’t forget to enable Caps Lock for quick switching between the English and a non-English (In my case, Devanagari) keyboard.
