Whether I use Copy as Text in the edit menu or Tag Copy as Text in the main window, %filename% does not seem to work. It is not flagged as an invalid tag but it just won’t copy the info to the clipboard. If I use any other tag, it works perfectly. Am I missing some subtlety here? Also, I checked for updates and I have the latest version.
The correct name is %_filename%
But why do the other tags work without the underscore?
Please see the documentation on mappings and other property variables.
The "why" question will not lead us anywhere.
