Google Chrome	70.0.3524.2 (Official Build) dev (64-bit)
Firmware Version	Google_Lulu.6301.136.57

Steps to reproduce:
# Turn on ChromeVox with ctrl + alt + z
# Go to Customize and Control Chrome menu with alt + e or alt + f 
# Navigate down the list, paying attention to the indexes.  


Actual:
New tab though Bookmarks read as 1 of 15 through 6 of 15. 
The word Zoom is skipped entirely and not read 
Zoom out read as 1 of 1
Zoom in has no index at all
Fullscreen read as 1 of 1
There is no number 7
Print through More Tools read as 8 of 15 through 12 of 15
The word Edit is skipped entirely and not read 
Cut, Copy, and Paste are 1 of 3, 2 of 3, and 3 of 3
There is no number 13
Settings and Help are 14 of 15 and 15 of 15


Expected: consistent indexes 
- Number 7 and 13 should not be missing entirely
- It is confusing that you would interrupt the middle of an index count with another set of indexes, only to resume again after that second set is done. 
- If cut, copy, and paste are 1, 2, and 3 of 3, then zoom out, zoom in, and full screen could also be 1, 2, and 3 of three since they are similarly grouped together.

Recommendations from devs should be made about correct behavior since I can see several different ways it could be implemented correctly.
