Anyone who has worked with me knows how much I enjoy working with mainly the keyboard alone. IntelliJ and Eclipse have great ways of doing things with the mouse, and as I’m finding out, Visual Studio has a plethora of them as well. Unfortunately many of them trigger hidden buttons or menu items that don’t exist. We accidentally turned on a “feature” of showing spaces as dots and took a while searching out how to turn if off as shown in the diagram below.

Visual Studio showing spaces as dots

If it ever happens to you, you apparently have to drag a button onto one of the menu bars in order to disable it. Otherwise try the short cut keys, CTRL-R followed by CTRL-W. Of course…
