this is probably the most difficult step, you need to pause your game. this can be done by pressing the 'esc' key on your sick gaming keyboard, careful not to nut while pressing your esc key.

see? the menu should open and you won't commmit ded by a combine or other ♥♥♥♥♥♥ npc

ok, now that your menu is open and your game is paused, get that hand down your undies right now and scratch your itchy family jewels, careful not to apply too much pressure or you'll lose a few children that you will probably never make because you're a lifeless gamer nutting to pictures of your primary school crush

now your itchy walnuts have been relieved of their itch and you can now unpause your menu and continue playing the game in comfort

carry on gaming, gamer...
