Tracks cloud drift wind targets with one keystroke.


You can use the X key in place of the right mouse button when tracking cloud drift winds. It makes one wind measurement for each pair of frames in the loop bounds without stepping through the frames.

For example, in a loop of three images, you would press the right mouse button four times to make two wind measurements. The X key will make the same measurements by reading the cursor displacement on each frame without advancing through the frames; it's handled through the software so nothing mechanical is seen. This technique is useful if you find consistent flow in a large cluster of clouds.

To use this function,

Press:  Alt X
