I just came back to say I had found out that very thing, oldbroad, thank you !!
When I find something on the list, the list appears on screen without my taking any action to get it there.
So, it will be interesting to see what happens if I manage to find ALL the items
EDIT :
Sorted !!
If I click on the magnifying glass that sits bottom left of game screen "the list"
does then appear on screen and bears a tick through any items I've found.
