show an item based another one

This functionality is not supported right now. However, in your case you can use type='file|dir' mode='multiple' as the Copy Item usually appears under these conditions.

I'm trying to remove default Copy item and add a manual copy item instead
but i get an error
remove (find='*Copy')
item (type='file|dir' title='Cooopy' image=icon.copy cmd=command.copy)

command.copy is used to copy a string to clipboard, it expects an argument:

item( title='Copy' type='File|Dir' image=icon.copy cmd=command.copy('Copy string to clipboard')

Commands that replicate file explorer's cut-copy-move functionality are yet to be added.
