Gradient shading in the Disassembly view shows the start of each function.

Solid shading in the Disassembly view shows the instruction at the address of the current PC register followed by any related instructions that correspond to the current source line.

In the left-hand margin of the disassembly view you can find a marker bar that displays view markers associated with specific locations in the disassembly code.
