In Details Mode, when I click on a blank area of the file display, Opus deselects the files/folders automatically, how to prevent this behavior?
That´s by design, i would say. You could use the checkbox mode instead. Following code toggles the
checkbox mode & maintains your selection when toggling back:
@ifset: CHECKBOXMODE=Toggle
Select FROMCHECKS
Set CHECKBOXMODE=Off
@ifset:else
Select TOCHECKS
Use Power mode. Allowing you to change what the mouse buttons do is what Power mode is for.
