How do I see changes in the git index?

Question

Say I do

git add foo.txt

Now, foo's changes are in the index (I'm assuming git was already tracking that file). Now, when I do git diff, I can't see the changes in foo by doing

git diff

Are there some extra things that git diff wants before it shows me those changes?

To show unstaged changes only:

git diff

To show the staged/cached changes only:

git diff --cached

To show both cached and uncached changes, compare the whole working tree to the named commit (HEAD):

git diff HEAD

ooh. Thanks! Why so many words for 1 concept! Let me see if I got this straight: staged (or cached) changes = changes that live in the index.

I came here looking for a way to see both the cached and uncached changes together, so +1 for mentioning git diff HEAD.
