Identify a program by the interface (part)

I have a program that I can invoke with the mouse and left click in the left side of my monitor (touching) . Then appear three points in the bottom of the screen, above the task bar.

what program is ?
I think is a program to control virtual desktops.

Best regards

I don't see what you mean by "touching". What if you right click on that program's icon and select properties? You might also run Autoruns to see if you can tell what it is.

If you mean the white dot with 2 gray dots on either side, that is a Windows screen, but not sure what it means.

 

Yes I think is a virtual desktop manager. But what program. I don't detect the process.
by this reason i am asking if someone know this interface or is familiar for him....

Is really difficult change from desktop of desktop of this program. At the present moment I get sometimes with quick movements with the mouse from part to part of the screen until I see a change in one of the points.
