I see. Well, if you use copy/paste it clears what's in the copy/paste buffer which was actually the point of the workflow (sorry I didn't specify clearly before).
I'm trying to automate several things for different apps based on the same workflow where I'm constantly emailing or sending links to my business partner in gmail, hangouts, slack, etc.
To send something in Slack, it would be like this:
Copy something from the web.
Launch slack desktop.
Command - K
Automatically type the name of the person I wish to find
Enter
Command - V to paste the thing I wanted to send them
I believe Keyboard Maestro has this ability to enter text without copy paste, so maybe I can make a shortcut to trigger an action using keyboard maestro for the 'typing' but it's a shame to have to use two apps.
Thanks in advance.
