Is there a Keyboard-Shortcut for updating all fields, tocs and indexes in MS Word 2011 Mac OS X?

You can update all fields in a document by:

1. selecting all of the content (Cmd+A) and then
2. pressing F9.

This will update all fields at once on Word for Mac 2011-2016.

I know this answer seems to be implied in the question, but I think it's the best answer and should be listed (the fact that other answers even are given implies that it is being overlooked).

[Command + P] followed by [Esc]

Advantages:

1. This is faster than the select-all method (same number of commands, fewer keys)
2. Fields in headers and footers are also updated (not accomplished by select-all method)

So in conclusion: no, there's no specific single shortcut to update all fields, and the alternatives are not superior to [Command + P] [Esc].

Using F9 didn't work for me, running MS Word 2011 on a Macbook Pro with 10.8.4.

An alternative solution I found is to select all the text using command-A and then press command-shift-option-U. You can find that keyboard shortcut by control-clicking on the field and looking for "update field" in the menu.

MS Word for Mac 2011

Command+A (select all fields in document)

Option+Command+Shift+U (to update all fields highlighted)

In Mac Word 2011, OS X Yosemite, the cmd-P, Esc did not update the cross-references in the footnotes.

To do both main body and footnote, I first placed my cursor in main-body, select All (cmd-A), update fields (Opt+Cmd+Shift+U), click OK when notified this can't be undone.

Then, I placed my cursor in any footnote area, repeated the select-All and update fields process.

Now my cross references are updated in both the main body and the footnotes.
