Point 1 - Point 2: Define viewport in source window
Point 3: Identify destination window

Command name



Shows a rectangular part of a source window in one or more destination windows. It should be noted that source and destination can refer to the same window.

If the command is started by a mouse gesture then the destination window is implicitly assumed.

In all other cases the destination window must be explicitly defined if the window layout contains more than one window. The destination window is identified by a digitized point or by typing its identifier. Since the identifiers are powers of two (e.g. 1, 2, 4, ...) a set of destination windows can be defined by adding the identifiers of all windows of the set (e.g. 1 + 2 + 4 for windows 1, 2 and 4). A destination set containing all windows is indicated by the identifier -1.
