Abstract
Techniques are provided for indicating workspace awareness using one or more of a write shadow, a read shadow, and/or a shadowbar providing an indication of operations performed at associated locations by various users accessing a same document. A write shadow may be used to indicate a position in a document being modified by a user. A read shadow may be used to indicate a position being viewed by a user. A shadowbar may be used to indicate areas of overlap among users with a shading and coloring indicative of a degree of overlap.
