How do you know if the wireless keyboard is turned on or off?

As suggested in the manual on Page 9 "To conserve battery power, turn your keyboard off when you aren’t using it.", I tap the power button when I get up and leave the computer to conserve battery power.

Problem, and the reason I am asking is that you might know when you turned the keyboard on, but say you turn your computer off and it is late, you've been shuffling papers around and then you don't remember if you turned the keyboard off, maybe you did, maybe you didn't. In any case, if you hit the power key again, you will be turning your keyboard on, or if you didn't turn it off then you will be turning it off. In busy situations it is easy to loose track of if it is on or if it is off, there is no way that I know of to know if it is on or off.

I would only hope that the keyboard would turn off, not just when it isn't pairing with the computer, but for the keyboard that is paired (mine is) it would be best if it turned off after a period of no use. Here is what one man, not an Apple tech, said about the A1314 keyboard he was selling on ebay:

"The keyboard automatically powers down when you're not using it and turns on instantly as soon as you start typing. This intelligent power management means you'll get up to nine months of battery life based on average usage patterns. It also has an on/off switch for when you're away from your computer for a long time."

This doesn't indicate how many minutes of no use it needs before it 'powers down' (doesn't sound as good as really being turned off) and it also doesn't address the issue of knowing if your keyboard is on or off via the power button.

Even my dog electric training collar blinks twice when it is turned on and blinks three times when it is turned off. The Apple keyboard needs two indicator lights, one to tell you if it is searching for pairing and the other strictly as an on off indicator. I'm not going to loose any sleep over this, but it does seem like somebody was sleeping in the design department as this keyboard is really cool, but it doesn't convey the basic on/off information to the user.
