A space tool that inserts space into or deletes space from a document is described. The space tool provides the user with feedback as to which objects will be moved when space is inserted into or deleted from a document. To provide the user with this feedback, the space tool identifies the objects that will be moved when space is inserted or deleted, and changes the appearance of these objects. For example, the space tool may gray out or fade identified electronic ink objects that will be moved. Alternatively, or additionally, the space tool may move identified objects in real time, so that their location continually corresponds with what their location will be after space has been inserted or deleted.
