This is a common question asked by many minecraft players who want to showoff their custom minecraft maps, how do you take an in game screenshot in minecraft?

The answer is very simple:
- Press F2 while in game to take a screenshot.

If you want to make your screenshots look more professional, you can remove the HUD and enter fullscreen mode before taking one.

To do this, simply press the following buttons while in game:
- Press F1 to remove the HUD.
- Press F11 to enter fullscreen mode.

These commands work on both singleplayer and multiplayer.

If you really want to go that extra mile, an additional way of making your screenshots look better is to install a texture pack beforehand.
