visual studio 2012 puts a small number in the top left corner of my screen

Question

I am wondering if anyone else has had this issue with visual studio (or a VS extension because I have a few installed) and what is causing this? The number goes away when I close visual studio and I have not been able to figure our what is causing this. The number is overlayed on my desktop and not just visual studio. It covers all other windows I have open as well telling me it's set to be always on top.

Anyone else come across this issue or what is causing it?

Answer 1

I figured it out!

This has been bothering me for years. I finally just sat down and solved the problem. Basically, VS has this little known feature where you can navigate through code lens with just your keyboard. If you press Alt for a couple of seconds, you will see numbers just like the ones that appear at the top of your screen above your current method. To fix it, just long press Alt again and the number should go away. If you have many VS instances open you might have to go through them one by one.

Answer 2

I don't have significant reputation to comment, but I am experiencing this both with VS2013 and VS2015 too. The only extension I have installed is Resharper.

My research shows that it is caused by the hover text / overlays from various components. The only way I have found to get rid of them is to close the Visual Studio IDE window responsible.
