Hey guys, some strange thing happened yesterday. I was chatting with my friend from Russia via skype and suddenly number "20" appeared in the chat window before I could finish typing my message. I was thinking I accidentally pressed CTRL-V and pasted it in the chat but it definitely wasn't the case. Is this some sort of a bug or did I mistype something on a keyboard resulting in this? I was thinking what was the exact cause of this occurrence?
I attached a video of this happening below
