Trying to perfect my first "solid" action. Where to find complete list of entries?

[oshunluvr]

The predicate action in Open with File Manger is:

X-KDE-Solid-Predicate=[ [ [ StorageVolume.ignored == false AND StorageVolume.usage == 'FileSystem' ] OR [ IS StorageAccess AND StorageDrive.driveType == 'Floppy' ] ] OR StorageAccess.ignored == false ]

However, this didn't work for me either. I must be doing something else wrong, sigh...

I have swapped out every line, line by line, one at a time, with the lines in Open with File Manager and no matter what, the Unmount action will not hide under any condition.

I'm at a total loss at this point

I also tried moving the action from my home to /usr/share/solid/actions and no change.

There must be some other mechanism at work that hides certain functions under certain conditions.
