macOS AppleScript to open Accessibility Options

[glycon]

I mouse and type with my head through macOS Sierra Dwell Control.

What am I doing wrong that the following AppleScript does not bring up the Accessibilty Options panel as literally pressing Option-Command-F5 does?

on run

tell application "System Events"

key code 96 using {option down, command down}

end tell

end run

Not sure, but you can get into them in a different way (on El Capitan anyway):

tell application "System Preferences"
   activate
   set current pane to pane "com.apple.preference.universalaccess"
end tell

That's good but I need this:

Opt-Cmd-F5 is the default shortcut.

Mmmm... unfortunately I'm still on El Capitan so I don't have that System Pref. You'd need to see if you can get hold of the panel's ID (which is what I did in my earlier example). The script below should give you a list of your System Preferences' IDs. If you see something that looks like it might be the one you need, substitute it into my earlier example.

tell application "System Preferences"
   activate
   set thePanes to (id of every pane)
end tell
choose from list thePanes

Thanks for trying to help me out. The panel seems to spawn from Assistive Control.app which appears briefly in Activity Monitor when I press the hotkey but I haven't located it yet to point Script Editor to it.

upon a reinstall in place of 10.12.2 that fixed a separate graphics issue now my script works as expected
