# Enable ChromeVox with ctrl + alt + z
# Attempt to use the shortcuts to lock the screen and suspend
lock screen, search + l: fail, conflicts with next list
suspend, shift + search + l: fail, conflicts with previous list

Workaround: passthrough using search + shift + esc then try those keys, works as expected

This bug was originally reported as part of  bug 691151 , isolating just the remaining conflicting shortcuts here.
