Errata

Sentence describes moving to the end of a word. But the two uses of the word "beginning" should also be "end".

Note from the Author or Editor:
This section should read: "Move insertion point to the end of the current word; if the insertion point is already at the end of a word, then it jumps to the end of the next word."

The sentence ends with "type "omw"."

It should read "type "omw", followed by a space or punctuation.

Note from the Author or Editor:
Should read" In this example, whenever you type “omw”, Pages will step in and replace it with “On my way!”

Last sentence ends with...

invisible again, click Choose View->Hide Invisibles.

It should not have the word "Choose" in the sentence.

This should read: "To make the Invisibles, er, invisible again, click View→Hide Invisibles.

sentence ends with

maintain the object's original dimensions.

The last sentence in the note has the functions ROUNDDOWN and INT reversed. The sentence should read...

While INT turns -1.5 into -2, ROUNDOWN simply ignores the decimal place and returns -1.

The first argument is B5 and should be B1 as follows:

=MATCH(B1, Product Name, find value)

Wow - there is an example here of a table reference 'Produces-1' in single quotes. I have no idea what this kind of reference means or if it is even legal - yet your screen shot implies you can do this. You should change this to be a normal reference or add a section addressing these kind of references and teach us what this is all about.

Note from the Author or Editor:
The formula should read:

=INDEX(Products-1::ID, MATCH(B1, Product Name,0))

The screenshot doesn't need updating, as there are no ' ' marks in the screenshot

Existing sentence says:
This is where your iDevice stores all your photos and other media.

It should say:

This is where your iDevice stores your photos and videos taken on your iDevice or loaded via the camera connection kit.

Additionally you should mention that there may many other albums listed if your iDevice has been synced with iTunes and Photos downloaded.

says "you can perform a Google search..."

kinda but it should say:

you can perform a search for the selected work by tapping Search Web. Your search will be via Google, Yahoo, or Bing - depending on your settings in Settings->Safari->Search Engine.

Note from the Author or Editor:
Should read: "If Pages comes up empty-handed, you can perform an Internet search for the selected word by tapping Search Web. Your search will be performed via Google, Yahoo, or Bing, depending on your settings in Settings>Safari>Search Engine."

middle of sentence says: "wait until the first app has finished installing, and then...

Throw away that section - there is absolutely no reason to wait for the first app to finish loading.

Sentence should read:

If you're hankering for a second or third iWork app repeat this process for the other app(s).

Note from the Author or Editor:
Should read: If you’re hankering for a second or third iWork app, then simply repeat this process for the other app(s)."
