Shortcut for rectangular light: Suppose, you are going to produce a rectangular light and for this purpose choose first point (hold shift to manage direction). By default, the rectangle light only glares on the front face of the plane. Sometimes, it is required to flip the light once it is generated to keep it to point in the exact direction. By applying this shortcut, you just click on a point and hold down shift and click on the second point to form it. Now, a blue arrow will be visible and it shows the direction to which the light is pointing to, just shift the mouse to the other side to flip the light, click again to finish.
Shortcut for dome light: By default, there is an elementary HDRI loaded while generating it. But, when you hold shift and click, then it does not contain any texture. You can hold control and click to load the texture while placing the light.
Shortcut for spot light: Generally, just click wherever it is required to generate a spot light, then shift and twirl the light and at the end make modifications in the settings. But, applying the shortcut, just hold shift and click on a starting point. Now, it becomes possible to shift the mouse to modify the direction of the spotlight. You can also get the option to modify the angle of the cone. Besides, you can select the penumbra angle also. It is also possible to fix the direction and view the impact of the spotlight comfortably.
