Hotkeynet comming back?

I think On/Off is better

Here's a good rule of thumb. When designing interfaces (whether it's a script language or the index of a book or the menu in a program), always pick the word that is most likely to pop into the user's mind.

Ttry it in an ordinary sentence.

"My cat jumped on the keyboard and pressed the key _____ by mistake."

Down or On? Which comes to mind?
