Since Apple removed contextual menu plug-ins support for 64 bit applications in Mac OS X 10.6, Shortcuts is currently the only known way to use contextual menu plug-ins in 64 bit applications.
In first mode, it allows you to assign a hot key combination to chosen menu item so you can select some object (file in Finder or text) and hit keyboard combination to execute the task normally performed by choosing that menu item.
In second mode, Shortcuts displays the menu with items populated by contextual menu plug-ins. It can be triggered by a keyboard hot key or from services item
Note: 64-bit version 2.1 available here . Requires macOS 10.13+
