HELP! Where is the equation editor in Office 2007?

You are jumping the gun a little here; I will get round to updating the eBook that includes this but, as you ask, here goes...

Equation Editor is a feature of Microsoft Word that enables the user to insert mathematical notation into MS Word documents. A must for Mathematics/Science/Engineering/etc practitioners.

Equation Editor makes math symbols available via a set of toolbars. Unfortunately, there are no keyboard shortcuts for the symbols, so they must be accessed using a mouse.

There is a process by which an icon for Equation Editor can be added to the Quick Access Toolbar in Word 2007.

It isn't surprising that, as an ex-Maths teacher, I believe that the icon for Equation Editor should be inserted as a matter of course on all computers in every organisation where learners have acces to MS Word.

Here’s what the Equation Editor icon looks like on the “Quick Access” toolbar in Word 2007

To place the icon on the Quick Access Toolbar, you must...

• Open the drop-down ‘Customize Quick Access Toolbar’ menu which is found to the right of the toolbar,
  
  
• and select ‘More Commands...’
  
• In the dialog box that opens, click open the drop-down menu under ‘Popular Commands’
  
  
  ...
  and select ‘All Commands’, as shown below.
  
• Scroll down the list that appears and locate ‘Equation’, select it...
  
  ...
  and click on the ‘Add>>’ button to add the icon to the Quick Access toolbar.
  

• ∏ Equation will now be added to the Quick Access Toolbar list...
  
• Click OK
  
  Hovering the cursor over the symbol opens a tool-tip showing the keyboard shortcut to open Equation...

Note: - that there are some other math tools are available in Word 2007, so you may wish to experiment with some of these as well.
