Action

replaceShortcuts

Posted by @FlohGro, Last update over 5 years ago

Please read the documentations of the included scripts (links to original actions are in the scripts)

You‘ll need an Action called „ShareDraft“ which will Share the draft by e-mail / clipboard or something else. If you dont have this action, you should disable the last step of the actions.
