|H/V LINE(S)||
This option allows you to create a stream composed of one or more horizontal|
and / or vertical line segments.  After selecting H/V Line(s), click on the 
body of|the module which the stream is exiting.  The stream may then be 
completed in|one of two ways.||
(A) You can immediately click on the body of a second module.  FD3 will then|
attempt to connect the two modules in as efficient a way as possible.||
(B) You can click on an empty part of the flow diagram.  If you do this, 
FD3 will|draw either a horizontal or vertical stream segment between the 
point on which|you just clicked and the point on which you previously 
clicked.  You may continue|adding stream segments until you click on the 
body of another module to|complete the stream.||
In general, method (B) is only used when the streams automatically created by|
FD3 using method (A) are unsatisfactory.||
DIAGONAL LINE||
This option allows you to connect two modules with a single line of arbitrary|
slope.  Click on the module which the stream exits and then click on the 
module|which the stream enters.  FD3 will then make a stream which connects 
those two|points with a single straight line.||
BUMPS ON / BUMPS OFF||
Selecting Bumps On causes FD3 to make little bumps where ever streams|
intersect.  Selecting Bumps Off causes FD3 to stop making bumps and to erase|
any existing bumps.|
