Show/hide Accessibility Keyboard with a keyboard shortcut in MacOS Catalina? I would like to display and hide the Accessibility Keyboard in MacOS Catalina using a shortcut.

The old solution from thread How to show or hide Keyboard Viewer with a keyboard shortcut? is not working since the update to MacOS Catalina. KeyboardViewer.app is not anymore in /System/Library/Input Methods/
A workaround I found was to use "hot corners" to toggle the visibility of the virtual keyboard. Unfortunately this does require using the mouse, just moving it to a screen corner to activate a command.

You can access the hot corners tab from the accessibility keyboard settings (gear icon -> Preferences).

The "Hide/Show Home Panel" is the default and correct option. I like to unselect the "Panel follows Hide/Show Home Panel" so the Panel doesn't move around.

Note that this will only work if the accessibility keyboard is activated. This is definitely not ideal (a bit ironic too), but it's the least painful alternative I could find. Hope it helps!
