\S{cmdCurve} Curved Track
\G{png.d/bcurve.png}
Creating a curve is a two step operation. The four methods (with their Shortcut keys) used to create a Curved Track are:
-\dd \G{png.d/bcurve1.png} (\c{Control-4}) Drag from one endpoint in the direction of the Curve at that point and release. Click and Drag to position the second endpoint.
+\dd \G{png.d/bcurve1.png} (\c{Control-4}) Drag from one endpoint in the direction of the Curve at that point and release. Click and Drag the red arrows to position the second endpoint.
+If Shift is held down when the first endpoint is being placed and the cursor is on a track, the new curve end will "Snap" to the nearest open track endpoint and you can drag out the second end aligned to that track. After a track is competed, the new track will be connected to this first track.
\u000
\dd \G{png.d/bcurve2.png} (\c{Control-5}) Drag from one of the endpoints to the Center of the Curved track and release. Click and Drag to position the second endpoint.
+If Shift is held down when the first endpoint is being placed and the cursor is on a track, the new curve end will "Snap" to the nearest open track endpoint and you can drag out the center at right angles aligned to that end. After a track is competed, the new track will be connected to this first track.

A drop down menu, which allows selection of the Curved Track creation method, is invoked from the down arrow button (\G{png.d/bmenu.png}) located on the right side the Curved track button.
