Behavior hasn’t changed it still works the same way. Occasionally, system automation experiences a glitch in the way it interprets timing between keystrokes. A couple of quick fixes, one of which should work:
• Quit and restart VoiceOver
•Save, quit and reopen session file.
• Open Flo Tools prefs and change the double-tap timeout
• If all else fails, reboot.
