Binds a specified fvwm command Function to an edge of the screen. Direction may be one of "North", "Top", "West", "Left", "South", "Bottom", "Right" and "East". If Function is omitted the binding for this edge is removed. If EdgeLeaveCommand is called without any arguments all edge bindings are removed.

Function is executed when the mouse pointer leaves the invisible pan frames that surround the visible screen. The binding works only if EdgeThickness is set to a value greater than 0. If a function is bound to an edge, scrolling specified by EdgeScroll is disabled for this edge. It is possible to bind a function only to some edges and use the other edges for scrolling. This command is intended to raise or lower certain windows when the mouse pointer leaves an edge. FvwmAuto can be used get a delay when raising or lowering windows. See example for EdgeCommand

Normally, the invisible pan frames are only on the screen edges that border virtual pages. If a screen edge has a command bound to it, the pan frame is always created on that edge.
