Sometimes the sending LED on my keyboard blinks green, and other times it blinks red. What's that all about?

The two colors indicate whether the keyboard is getting through to the computer successfully. Green means keystrokes are getting through. Red means something is wrong and keystrokes are not getting through.

You can try the following experiment. Unplug the receiver from your computer and type a few keystrokes. The sending LED should blink red.

Then plug the receiver in and type again. Now you should see green LED blinks. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
