Type the "Ohm" Symbol with the Keyboard

Ok I know it's an O but it's open at the bottom and how to change it to a "Symbol" character as you say ???? (Is there a "symbol" key on the keyboard ??)
I've done plenty of tries with Alt and a number but haven't found it, !!
It's like at the lottery, there are thousands of possible combinations !!!
On my keyboard I can get Diameter (the O with a diagonal line through it with alt +157 = Ø
the Ace of Spades >> alt+6 > ? ) it doesn't display here! It shows "?"

on a clear night I believe after searching everywhere that the omega letter of the ohm symbol ?????? does not have a keyboard shortcut but nothing prevents you from creating one ;)

open Word, then go to the Home tab, Symbols group, Symbols button, More Symbols
then select the symbol you wish to assign a keyboard shortcut
click on the Shortcut key button, in the "new shortcut key" box, type the one you want (it can be a combination with Alt or Ctrl or both)
if the key is already assigned, Word will let you know click on Assign, then on Close

Your > combination, >> ALT + 8486
On my machine it gives me > & <<
Someone had given me alt + 937 > on my machine = ®
so it's not the same from one PC or brand to another ????
