UPDATE (July 11, 2013): I was asked the following as a response to this post: “How do you click the chrome screen if it isn’t even on the screen.” Fair question. Answer: If you’re on a Windows machine, use the key combination ALT+TAB till you are positioned on “Chrome” (and there’s probably an equivalent action for other machines.) You won’t see the window, but it will now be the “active” window. From there follow the instructions in the post.
Follow the instructions at the top of the post (in the July 11th, 2013 update, in maroon) in order to make the Chrome browser the “active” window before continuing with the next step.
Press Alt + Space: This opens the the “Window Menu.”
Choose “move” either by clicking on the option if you can see the menu, or by hitting the “M” key.
Hit one of the “arrow” keys, the one with a direction opposite to where your browser window has gone (mine went to the right, so I hit the “left arrow” key) enough times until you can see the enough of the browser to be able to drag it.
Drag the browser to the desired position.
Close the browser (this is important in order to ensure that this new position of the browser is saved and will be the position of the browser the next time you open it. Skipping this step means that the last saved position is “off screen”. Should the brower close improperly, it will re-open in the last saved position, that is “off screen” and this procedure will need to be repeated.)
Re-open you browser and proceed normally.
