Sending keystrokes in Applescript via Automator in any application

There are issues at play here with using global keyboard shortcuts with Automator workflows saved as a Service/Quick Action.

• The keyboard shortcut assigned to the Service/Quick Action needs to not conflict with a default keyboard shortcut for whichever application is frontmost at the time it's pressed, otherwise there may be unwanted behavior.
• Every application that is frontmost when the keyboard shortcut is pressed on a Service/Quick Action using UI Scripting in the Run AppleScript action will need to have accessibility privileges granted for it (as you've already found this out and hence the question).

To workaround the accessibility privileges issue, here are three methods to achieve the goal that come to mind.

• The first, my preferred method for running AppleScript scripts with a keyboard shortcut, is to use a third-party application named FastScripts, as it would not need to have every application that's frontmost, that hasn't yet been granted privileges, to be granted accessibility privileges to run the AppleScript code shown in your question. I'd imagine other similar type third-party applications that allowed assigning keyboard shortcuts and running a script would bypass the issue too, but have only tested the aforementioned.

• The second method, can be done with Automator as a Service/Quick Action using a Run Shell Script action, then assigned a keyboard shortcut and will work without having to give accessibility privileges to the application that is frontmost when the keyboard shortcut is pressed.

• The third method, can be done with Automator as a Service/Quick Action using a Run AppleScript action if changing a zoom.us default preference under zoom.us > Preferences… > General by unchecking [] Ask me to confirm when I leave a meeting, then when assigned a keyboard shortcut and will work without having to give accessibility privileges to the application that is frontmost when the keyboard shortcut is pressed.

All testing was done under macOS Big Sur using zoom.us, (Version: 5.4.7 (59780.1220)) with my Language & Region setting in System Preferences set to US English using the various methods presented.

Method 1

The first method using the following example AppleScript code, show further below, and FastScripts with the keyboard shortcut ⌃⌥⌘W assigned and works for me as coded.

In System Preferences > Security & Privacy > Privacy > Accessibility I had the following added and checked:

• FastScripts
• System Events

Then with zoom.us running and several other applications which were frontmost when the keyboard shortcut was pressed I did not have to grant accessibility privileges to those other applications, zoom.us was brought to the front and closed.

Example AppleScript code:

if application "zoom.us" is running then
    tell application "zoom.us" to activate
    delay 0.5
    tell application "System Events" to ¬
        tell application process "zoom.us"
            keystroke "w" using command down
            delay 0.5
            key code 36
        end tell
end if

• _{Note for testing purposes, after testing Method 1, I quit FastScripts as it would have been triggered by the same keyboard shortcut which was assigned when testing the next two methods.}

• _{FastScripts can be run as a free app, up to 10 keyboard shortcuts, or upgraded for $24.95 USD to unlock unlimited keyboard shortcuts. I have no affiliation with Red Sweater Software, LLC, other then as a user of FastScripts.}

Method 2

The second method was tested using Automator and a Service/Quick Action with setting Workflow receives [no input] in [any application] using a Run Shell Script action with its default settings, and the following example shell script code is all that was used:

[[ -z $(pgrep -x 'zoom.us') ]] || pkill −x 'zoom.us'

In System Preferences > Keyboard > Shortcuts > Services I assigned it the keyboard shortcut: ⌃⌥⌘W

Then with zoom.us running and several other applications which were frontmost when the keyboard shortcut was pressed I did not have to grant accessibility privileges to those other applications, zoom.us was closed.

Method 3

The third method was tested using Automator and a Service/Quick Action with setting Workflow receives [no input] in [any application] using a Run AppleScript action replacing its default code with just the following example AppleScript code:

tell application "zoom.us" to quit

In System Preferences > Keyboard > Shortcuts > Services I assigned it the keyboard shortcut ⌃⌥⌘W after removing it from the Service/Quick Action created in Method 2.

Then with zoom.us running and several other applications which were frontmost when the keyboard shortcut was pressed I did not have to grant give accessibility privileges to those other applications, zoom.us was closed.

This of course works because the [] Ask me to confirm when I leave a meeting preference was unchecked in the preferences for zoom.us.

To recap, if you do not mind changing the mentioned default preference in zoom.us, then Method 3 is probably the easiest and best way to resolve your issue as it allows for a graceful quit over Method 2, does not require any third-party application, and does not require any accessibility privileges be granted or zoom.us being frontmost, it just works.

I mentioned the other methods first as method one addresses the UI Scripting issue with Automator and a Service/Quick Action, and method two works with the default settings in zoom.us.
