Quick screen capture and edit sketch a dot

Hello, is there a way to sketch in the quick screen capture using the BTT sketcher. I want to sketch just a dot? it doesn’t look like it exists in the sketching tools! The only way is to use the pen and sketch lines, no dot.

Thanks

you mean in the macOS "markup editor" that BTT uses?

Ok, but this is drawing a filled circle. I am looking for a dot, or point. I want to click the mouse button once and generate a dot with a preset size. I only see in the ketch, but I can create lines, and scribles, but when I click the mouse it doesn’t generate a dot.

In other word, how can you sketch the letter i with a dot on top? it seems like a basic sketching tool!

Thanks

I think this is not supported by that markup editor (it is provided by the system, the same is e..g. used in notes)
