Dear community,
I am trying to find the keyboard “shortcut” for this sign (which I now copied from the references page):
||
It is the sign for “OR”. I am currently using a Mac (High Sierra 10.13.4) with a german keyboard.
Help is much appreciated :).

alt+maj+L
I don‘t know for mac, But for german Keyboard it’s in General Strg+Alt+<. Though might be different for mac. Probably something like Ctrl+alt+<… Or there somewhere. 
just in case it‘s not working with +L…
oh boy …
thank you guys very much for the fast answers!
unfortunetally nothing has worked so far. I have pushed several options now up and down my keyboard but so far nothing … found the root and rubel signs though :D.
Try shift +/ or \ . This might be it. Or alt+7.
Halleluja!
alt + 7 did the trick for me!

Thank you!
