When in Finder and I press ⇧⌃⌥O, this makes an error tone, of course, because that is set to do nothing. If I set ⇧⌃⌥O as the Hotkey for the workflow "Right Click — Trigger a right-click on Finder files, with the keyboard" then I no longer get the error tone when I press ⇧⌃⌥O, I get silence, which is what heppens when finder or a program normally does something from a shortcut. Which leads me to think that it's activating the workflow but the script isn't working because the item that is highlighted isn't being right clicked.
I recorded a video but mp4 file types are not accepted at attachments here? I could upload as a gif, but it wouldn't have the audio and error tone...
