Repro steps:
# With ChromeVox running, open ChromeVox options
# Choose the button to change the voice
# Use arrow keys to navigate the menu

Expected: Works as expected usually

# Use search+left and search+right to navigate the menu

Expected: the options are read with the current voice and the new choice only goes into action after enter or search+space

Actual: The voice is changed unpredictably whilst navigating the menu

To clarify, using Search+Left/Right was previously triggering the menuitem. This is no longer the case on the latest builds of Chrome OS. Please give this another try.

When arrowing up/down (without Search), there is noticeabl edelay while the voice is being loaded. This is unfortunately the current state of voice switching in Chrome OS but we are aware of that particular issue.
