It appears that sometimes when I am editing a javascript file in Visual Studio 2010, the IDE will just stop responding to my keyboard. Thinking it was my keyboard I tried unplugging and re plugging it back in to see if it is a USB issue and that doesn’t fix it. I actually found a bug report to Microsoft located HERE to which there are no solutions provided, just a “We are planning on fixing this in the next version. I will report below some of the things that I have done that have brought the keyboard back for me in case you run into this problem yourself.
1) If I press Ctrl+Shift+Caps Lock+Tab all at once it seems to free it back up for me.
2) CTRL+TAB either once or twice seems to do it as well.
3) Sometimes, closing and re-opening the specific code window I’m working in fixes it.
I hope this fixes this issue for you should you happen to run into this problem.
