Hi

How to read only the second filename in the %S2 variable?

Maybe use %C2 instead?
%C2 works like the second parameter of "Compare by content": Second selected file, or first selected in target panel (if there aren't 2 selected in the source panel), or file with same name as the one under the cursor in target panel if nothing is selected in the target. Note: If the right panel is active and less than 2 files are selected, %C1 and %C2 will be reversed.
