I recently upgraded to El Capitane and am faced with the following issues in TEXtEdit:
1) The behavior of the arrow keys (without VO keys) is erratic.
2) VoiceOver suddenly stops speaking characters.
3) VO + A to read text from the VO cursor, stops reading mid way.
Is anyone experiencing these issues? Are there any workarounds? Resetting VOICeover sometimes helps with Issue #3.
