Sending a signal after n seconds

[brained]

Hi all, I'm just wondering something. Can you wire a button with some sort of device that enables the button to send a signal after a few seconds. For an example, just like the pc power, if you press power for about 4 seconds the pc shuts down.

I want to do this because I don't want to accidentally press esc while playing a game.

I think capacitors are the thing  for this situation.

You could use a 555 timer to build a delay circuit.  You could add a variable resistor to adjust the delay.  Here is a diagram to get started.

Instead you could try a pushbutton with a cover or use a shift key.  Also if you are into AVR chips, you could program an AT90S2313 to act as a delay circuit.
