Hello, I have a very old Toshiba (Satellite 645series) and it had this "helper/shortcut" rectangle thing(forgive me I'm not the most tech savvy and am not sure of the terminology) hidden on the side of my screen display that if i touched the edge of my cursor would open to full-size (meaning the Toshiba rectangle with icons) and i could just click on it. In a moment of distraction, I closed it rather than "hiding" it back and do not know how to re-open/where to find it. If anyone knows what I'm talking about, suggestions of how to find/fix it are welcomed. Any ideas? Many thanks.
