Note: You are currently viewing documentation for Moodle 1.9. Up-to-date documentation for the latest stable version is available here: Sharing Cart.
When a content item is in the sharing cart, the "move into folder" icon looks like a -> arrow (traditional Moodle - it is a right "move" arrow). I've tested this using the "standard" Moodle theme. So, in the instructions, it is not click on "edit icon", it should be click on the "move" icon - that is, unless the icon is changed at the code level.
