@politicus - Thank you so much for this. Once I had started reading this thread, I had given up because it seemed to complicated. I really appreciate you sending me the workflow. Made it very easy to do. I just tested it and it works perfectly.
And thank you everyone else who replied. I appreciate you taking the time to help.
@deanishe I guess so but thanks to @vitor's answer and a few more trials and errors better understand pbcopy and pbpaste I found a solution.
@vitor Thanks for the explanation.
Before trying my solution, I red this article that says:
This (pbpaste) will print whatever data you copied from the pbcopy command or the Finder's copy command (command-c).
I also red this article that says:
You could grab the output of a grep/awk/sed to paste into IM/IRC.
I, then, thought that running my script would copy "http:www.zoom.com" to the clipboard plus, not then, paste the content of the clipboard to the frontmost application. Maybe, I confused "print" with "paste" in the first article. Plus, I didn't know about pbcopy and pbpaste input/output.
With your answer in mind and playing around a little more with Alfred actions, I found two different ways to make it work.
(BTW, I am curious to know how you added a grey background to pbcopy).
@Zero Cool Here is the file of the workflow. Download it here, set the keyboard shortcut you want. Replace "htttp://www.yourzoomurl.com" with the url you want in the "Copy to Clipboard" action.
