a...Round (emphasis on R strongly) --> CTRL+R , as in around the object. does it work for you sir, madam, miss? ^^
The video teacher was asking: how can we remember the loop cut keyboardshort cut, I answered: CTRL+R, I answered: a-Round, Remember the word around with focus on the R, Then CTRL+R is easier to remember.
I was thinking "Ring"! Since edge loops are often just that (a "loop"), they could also be referred to as "rings". Either way, we have methods to remember now :D
