Whenever I accidentally press the power button on my MacBook, it switches off the display. This behaviour change happened from OS X Mavericks (10.9).

Earlier it used to let us choose with following options:

OSXDaily.com has got a workaround for this trouble. It does not straightaway enable these options the moment you press the power button, but it prevents OS X Mavericks from switching the display off, which is far more relieving.

To invoke the above power button options: press power button continuously for a second or two.

Thanks OSXDaily.com.
