You see, back in Acrobat X, when we ran actions using the Action Wizard, they simply ran when we clicked on the action name. The first time we'd run the action, we'd just have to click once on the "Don't show again for this Action" dialog box. It was so efficient!
The only additional user interaction that was required was an acknowledgment that the action was completed. And I don't even count this as a required click, since I can dismiss the dialog box using my keyboard.
But so several other of my favorite Acrobat features, this one was removed in subsequent versions of Acrobat. I imagine it was part of a greater Acrobat Wizard "enhancement," but if you have older Acrobat actions that you don't need to edit, and just want to run with one click (as they used to), here is the workaround.
1. Go into Acrobat X Action Wizard Pane and select Edit Actions.
2. Select the Action you want to run with 1-click in Acrobat XI. Then chose Export.
3. Save the Action.
4. Go into the Action Wizard in Acrobat XI. You will get the following dialog box:
"The action appears to have been created with Acrobat X or earlier. You will be able to run the action, but it will not take full advantage of the new Action Wizard features in Acrobat XI. Do you still want to import the action?"
5. Click "Import" to import the action. Then Click "Close."
Now the action will run with a single click in Acrobat XI. Of course, you can't edit, rename it, copy it, or export it here in Acrobat XI, but that's fine by me. I just wanted a way to run this action without having to click three times.
