How to display %1 value in script?

Some buttons, such as Edit > Paste, have tooltips ending in %1: Paste files and folders on the clipboard to the destination folder\n\n%1. In Paste's case, it displays the current text on the clipboard if any is present.

Is it possible to show this for the tooltips of buttons that run JScript / a user-defined JScript command? And is there any documentation that talks about the %1 argument?

I'm also curious if my own JScript version of the Paste button can show as disabled in the same cases as the default Paste button, i.e. when browsing "This PC" on Windows 10, the Paste button is disabled.


- Directory Opus v12.23.4 Beta x64 Build 7769
- Windows 10 v20H2 OS Build 19042.906

There's no way to use %1 in tooltips for custom commands.

I'm guessing it has to do with the virtual folders such as the Recycle Bin, This PC, etc. DOpus doesn't directly manage them in the same way it manages normal folders. I'd like to find out if there's a "virtual folder" flag.
