A user is enabled to select multiple objects in a document which is opened in an editor and contains selectable objects by presenting each of the objects as an entry of plurality of entries in a separate window; allowing the user to select multiple entries; and selecting multiple objects corresponding to the selected multiple entries in the editor based on the entries selected by the user. An Assistive Technology application may be called to provide related information and selection state of the operated object based on a user's operation on any one of the entries. The multiple objects can be selected in the document with a keyboard to help disabled users, such as low vision users or blind users.
