Hi, @Toni Cuea
One solution would be setting up through control panel. You can enable it in Control Panel->Mouse Properties->Pointer Options->Show location of pointer when I press Ctrl key. Pressing Ctrl will animate a shrinking circle at the location of the cursor.
You can also press alt shift or control. It will bring up a little box to say that you pressed that key, and the box follows your cursor.
The size of the pointer cannot be adjusted, you can use the feedback function of OneNote to give some advice.
