How to find members using MRN

I'm new to using this feature but I'm a stake clerk and I just dont know to do this but i need to know how to search for a member using their mrn. Sometimes when i'm activating recommends some clerks still use paper copies. Sometimes its hard to read some bishops handwriting of the name but i can read the mrn. is there a way that i can search for a member using their mrn?

In LCR, the find members, reports and forms search box will take a name or an mrn to find people.

Thanks so much. Sounds like it’s pretty easy thank you.
