"Filetype SUMMARY All" and "Filetype SUMMARY Selected" Codes in Buttons

Use "Filetype SUMMARY=all" All to show a summary for all files in the folder, even if some files are selected.

Use "Filetype SUMMARY=selected" to show a summary for only the selected files in the folder.

If no files are selected and/or only folders are selected, both commands show a summary for all files in the folder.

That's what the commands do. Did you want to ask a question?

I have no question. This is documentation of commands not yet documented.

The commands are documented (see the Properties command), just not the UI yet (but it’s largely self explanatory).
