Now then, I worked through this a few times and up to this point don't think I had much of a problem...or maybe I was asleep/in another dimension/dead but I get to this point:

I find my value and select "Find out what ACCESSES this address" which is different from the previous step 5 tutorial using "Find out what writes to this address".

The tutorial text states, "Change the value again, and a item will show in the list. Double click that item. "

However, I always get 4 items!

What am I missing here? Maybe I am tired and cannot think clearly.

You were told to find what writes to the address but you found what accesses the address, which also shows instructions that read from the address. The second one in the list 10002CADC - 89 02 - mov [rdx], eax is the one that writes to it (mov destination, source. with [] = "[memory value at address]", without = "value")

AH. Thanks. I was tired and should have known better.

However...

I cut/paste the text from the TUTORIAL itself.

"First find the address of the value. When you've found it use the function to find out what accesses this address."

You will notice that it does indeed state "what accesses" and not what writes.

Maybe the author should correct their mistake.

Nope, find what accesses is what you should use as a pointer may not be written.
But the tutorial is designed for 32-bit, and you've targeted the 64-bit one, so somethings are not 100% correct and thus a bit more challenging

In your case there's not just one, but multiple. To have an easy time, just pick the writer instruction, but if you wish to understand what happens instead of blindly following a track, pick the read instruction:
