Adam mentions the WebGoBack command, and this seems to do the right thing. In Word 2011, WebGoBack is not listed in "All Commands" in Tools->Customize keyboard..., so you cannot assign a keystroke to it in there, but it does exist.
Whether it is missing from the "All Commands" list deliberately (e.g. because it's unreliable or unsupported) or accidentally, I cannot tell you. But you can create a macro in Normal.dotm that invokes it, and assign a keystroke to that:
Sub myWebGoBack
WordBasic.WebGoBack
End Sub
or you can use a one-off piece of VBA to assign the command to a keystroke. e.g., this code assigns the command to the Option+Left Arrow key:
Sub AssignOptionLeftArrowToWebGoBack()
CustomizationContext = NormalTemplate
KeyBindings.Add KeyCode:=BuildKeyCode(37, wdKeyOption), _
KeyCategory:=wdKeyCategoryCommand, _
Command:="WebGoBack"
End Sub
If you would rather use a different key, use a different Keycode - e.g. to assign Option+comma (on my keyboard the "<", which I can think of as a left arrow, is above the ",") you can use:
Sub AssignOptionCommaToWebGoBack()
CustomizationContext = NormalTemplate
KeyBindings.Add KeyCode:=BuildKeyCode(wdKeyComma, wdKeyOption), _
KeyCategory:=wdKeyCategoryCommand, _
Command:="WebGoBack"
End Sub
To clear all the assignments to WebGoBack (so that Option-Left Arrow reverts to its "word left" function, you can use
Sub ClearWebGoBackKeyBindings()
Dim kb As KeyBinding
CustomizationContext = NormalTemplate
For Each kb In Application.KeyBindings
If kb.Command = "WebGoBack" Then
Debug.Print kb.KeyString
kb.Clear
End If
Next
End Sub
The WebGoBack function in Word for Mac 2011 seems quite broken. I've tried
shift+F5
and the above myWebGoBack subroutine, but both seem to randomly work sometimes and not others. Where you actually go back to might be some previous anchor or link, or the start of the document. Pressing it multiple times goes around in a sequence, but it's likely that none of the destinations is where you started. – RobG – 2014-08-14T06:00:30.507
