nit: please run 'git cl try' after uploading the next patch set, it would be
good to double check there are no regressions and that the modified tests pass.

[yiyix, 2017/05/15 22:55:15]

I did it in the other patches. I did several patches before submitting this one
(as shown in the generated messages.) I will remember to include the result in
the final version.

The spacing around the + signs should be consistent with the spacing on line
190. We should pick whichever of the two options is read back correctly by
ChromeVox (I suspect that will be the one on line 190).

Sorry, I forget to update it as i copy it.

Should be ChromeVox instead of Chromevox

[yiyix, 2017/05/15 22:55:15]

[tdanderson, 2017/05/08 21:55:27]

I suspect that it is sufficient for IDS_ASH_STATUS_TRAY_SPOKEN_FEEDBACK_ENABLED
and IDS_ASH_STATUS_TRAY_SPOKEN_FEEDBACK_BRAILLE_ENABLED to just say "Press Ctrl
+ Alt + Z to disable spoken feedback." (in which case you can delete one of
them).  I don't see any reason why only one should say "Spoken feedback is
enabled"
