F2 allows renaming of the selected object or, in some contexts, the slide (by selecting slide title). However, F2 in thumbnail pane doesn't rename; but it's standard rename key.

Better question: In Excel, F2 edits cell. I'll replace. I'll skip this and create another. Need 300, I'll replace with a valid question. I'll do: In MS Access, what is the maximum size of a database? A) 2 GB, B) 1 GB, C) 4 GB, D) 500 MB. Actually, Access 2016 max is 2 GB. So that's ok. I'll replace question.
