In PS Elements left clicking a brush followed by Shift+Click in another location will draw a straight line.
In Lightroom its possible to left click the adjustment brush, then enlarge the brush with the arrow keys, then Shift + Click to draw a straight line cone. This is useful, for example, when painting on dramatic light rays.
I would love to use a brush to draw a straight line cone in PS Elements using the shift + click method. I have tried withgout success. Is this possible? Your advice would be appreciated.
I'm not sure if I fully understand you with respect to how you are drawing the cone. But, you can create a Brightness/Contrast adjustment layer and use a brush to paint the light cone on the mask. You can use shift-click to draw a straight line on the mask. Here is a crude example. (The lines are not completely straight because I quickly filled in the cone between the lines.)
