In the IconBar hover over a [Global Script button], right-click, select Goto Script.
If the file is currently open, then the cursor switches to the file and lands at the correct node in the @button list.
However if If the file is NOT currently open, then Leo opens the file, the cursor doesn't land at the correct node in the @button list; it appears to land at the middle of the @button node list.
With the file now open, Goto Script behaves as expected.
