have been something that came with the computer for me.
I recently had one that wouldn't work on some of the keys....sometimes, like when
I needed to log-on.
So I had to buy one. Took a while just to find one because they are so proud of them.
I finally got one, a
Logitech wireless K800 backlit.
Never had a backlit and sure like that.
Didn't like having a wire...not for a DAW. They're just to short for my setup.
I like the way the lights are off until it senses you're near.
It has an on-off switch and recharges with a USB and can do that while it's in use.
Thought I'd give it a mention and a thumbs up in case anybody's looking.
