How to use Greenshot to Mark your Images with Text, Arrows, and Shapes on Windows
Here are the tools available on Greenshot to mark images with text, arrows, and shapes, followed by examples.
Greenshot has the following tools to edit your picture:

Add Text (shortcut T): To expand the text box, click and hold your mouse button like you did when taking the screenshot.

In the text settings bar (above the picture), you can select fill color, text color, font size, font type, etc. If you don`t want shadow under your text, click on the Drop shadow icon in the text settings bar:


Draw Arrows (shortcut A): Click and hold your mouse button to decide the direction of your arrow.

In the arrow settings bar above the picture, you can select the thickness of the line and whether your arrow has arrowheads at the start, end, or on both points. You can also drop shadows like in the text version.


Draw Lines (shortcut L): Click and hold the mouse button to select the direction of your line; hold Shift if you want a perfectly straight line. You can change line thickness and drop shadow in the line settings bar.


Draw Rectangles (shortcut R): Click and hold the mouse button to define the area of your rectangle.

If you want a transparent rectangle or a rectangle filled with color, pay attention to the fill color icon:


Draw Circles (shortcut C): Click and hold the mouse button to define the area of your circle. The fill color, thickness, and drop shadow work precisely in the same way as with the draw rectangle feature.


Obfuscate (shortcut O): Use this to blur text or any part of your picture. You can increase pixel size in the obfuscate settings bar (above the picture) to increase the degree of blurriness.


Add Counter (shortcut I): This is useful if you want to show a step-by-step process. You only need to click on different points, and Greenshot will add the number counters.

Other functions are available, like adding speech bubbles, highlighting, adding effects, cropping, or turning the image clockwise/anti-clockwise.
