Using Paint or Gimp WHERE is the UNSELECT?

Why with paint and gimp both do I see all these drawing, selecting options and no clear unselect?

Is there a way to unselect any of the drawing or selecting methods then I can go and reselect what i did earlier without drawing another circle when I mean to select it. ?

Under the 'Select' dropdown menu on the top of the page click 'None'. Or Shift Ctrl A is the shortcut. This is just to deselect without another action.

In the case of Photoshop, deselect can be toggled by pressing Crtl + D on Windows and CMD + D on Mac. In the case of Gimp, I normally switch to Move tool to use as a cursor (M) - it works in the same way as PS pointer. Also if you want to deselect an area that you have chosen, ctrl+alt+A would work.
