Actions are now a separate panel. From the menu go to:
Window >> Actions
You should find several built-in actions which can be used by selecting and clicking the play button.
To add third party actions click the pull down menu (top right in the panel with horizontal lines) and choose “Load Actions”
Then navigate to your .ATN files.
Why have I been able to put them in the effects panel previously? Even in 13 with the action window, I had some in the effects panel. I prefer them to run from the effects panel than a separate window. There has to be a way to get them to show up.
In older versions of PSE it was possible to use third parry actions from the effects panel but these required two files e.g. an .atn file and a .png thumbnail
They were stored in the following location
Computer OS (C:) >>Program Data >>Adobe >>Photoshop Elements >>9.0 >>Photo Creations >>Photo Effects
My PSE 2018 does not have the Photo Effects folder. I think Adobe has tried to simplify the process.
You could try creating a new Photo Effects folder and then adding the appropriate file pairs. Let us know if it works.
I have Photoshop Elements 18 for Windows.
I have an effects folder, I found that, copied my items to it and can not get them to show up for anything. The preloaded actions show up.
The file path will be:
Computer OS (C:) >>Program Data >>Adobe >>Photoshop Elements >>16.0 >>Photo Creations
yup! That's where I put them
If you load just the .atn file into the actions player does it work?
They run, but you can't see the names of what they are.
