My understanding is that this will be addressed in the next Steam patch; however, I'm pleased to report that in the meantime I finally got things working for the following menu commands:
1. Drop Item - the menu says "Press R"; however you need to use the key controlling your "Ready Weapon" function to drop items.
2. Spend Dragon Soul - the menu says "Press R"; however you need to use the key controlling your "Ready Weapon" function to spend dragon souls.
3. Give or Store Item - you need to use the "R" button (or remap the "R" button to something else outside the game using your Numpad or Mouse software)
4. Take All - you need to use the "R" button (or remap the "R" button to something else outside the game using your Numpad or Mouse software)
5. Take Book - once you open a book to read it, you are prompted to "Press E" to take; however, if you have remapped your "Activate" function to a different key or mouse button, then neither the "Activate" key nor the "E" button on your keyboard allows you to take the book. SOLUTION: outside of the game, remap the "E" key to your Mouse3 button (or whatever you want to use for "Activate") - this allowed me to finally take books and complete the quest where you have to steal Frost's identity papers.
Developer team member socrates200x posted some helpful comments in the last thread:

I figured it would change, but no luck.
I can get the 'add/remove favorite' shortcut to work but only when looking at a container. If I just go in inventory, it doesn't work.
Also I use a keyboard key for my left hand attack... I'm unable to change the weapon in my left hand as that key doesn't work. It displays MB1/MB2 to equip weapon (even though MB2 is not an attack key for me), and even so doesn't work anyways.
It seems if you bind something else to the keys mentioned as being shortcuts, they get overwritten, but it doesn't change to where you remapped it.
And the fact that the 'F' for favorite/unfavorite works in containers BUT not in inventory seems to indicate that something is broken...
That is as planned. Basically, the fall-back logic for the user remapping their keys around is to try to match the new anologue. In the menu, 'F' is Favorites, but in-game, it's Toggle POV. So, the menu uses the Toggle POV key to favorite/unfavorite. Ideally, you'd be able to remap menu keys separate from gameplay keys, but just one of those "I wish I had more time" things...
Anywho, thanks for the mapping info! I'll track this down today.
The fix will be rolled into the next Steam update. Sorry again for not catching this before release. Our remapping testing only goes as far as our creativity during development, which always falls short of how many different ways people conceive of bending their fingers. =P
Just so I and other devs don't constantly have to pop in to say it, keep posting any problems you're having. Soon, if not already, there will be a (very full, I'm sure) Skyrim Bugs sub-forum. We'll be watching, we'll be fixing, always fixing... Enjoy Skyrim!
