The Compress Selected Items is a command that can be found using:
- Bundles → Select Bundle Item… (⌃⌘T)
- Enter
compress
- Press option-return (⌥↩) to edit the item found
On the last line the (just updated version) has:
%x{tar -cjf #{dest_path.shellescape} -C #{dest_dir.shellescape}/ #{relative_paths.shelljoin}}
Change this line to call zip instead, e.g.:
%x{cd #{dest_dir.shellescape} && zip #{dest_path.shellescape} #{relative_paths.shelljoin}}
Also change ".tbz"
in line 31 to ".zip"
