Re: Spoilers in Tech Docs!
While true you have to remember the target audience for any documentation. You'd be surprised how many people ask "what does press button mean?" and when presented with the answer reply "well why didn't you just say click it then?"
Your average user associates "click" with the sound the mouse makes when they press the virtual button on the screen. It's all very Pavlov, but yes, if you want to get your point across to the average user it's safer to say "click button x" than it is to use the more logical "press button x".
