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).

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

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"
