This first happened about 2 weeks ago and only 4 times and only on Google search at Google.com. I type in a search phrase and go about searching as normal. I decide I need to change a word or 2 in my phrase. I position the cursor in the text box, delete the unwanted word and start to type a new one. When I start typing, the command box ( alt + f2 ) pops up and the text is entered there instead. It doesn't do this all the time and I catch it when I proofread. It is just very strange. Is it my machine or is Google having fun with code?
