Get multiple keypresses in a sequence?

Hey guys. I’m making a cheat code for my game, where if you press certain letters on the keyboard in a specific order (basically, if you type something in), it will enable a post process in my First Person Character BP. Currently I’ve just got it set to an action mapping, but I need to know how to make it so that it will enable it if you press the specific letters in order (IAMCHEATING). Thanks!

if any letter from the word is pressed, check current cheat variable, if new letter fit add it into variable on last one activate cheat, but if new letter dosnt fit, clear variable.

Could you explain how to do this? Sorry, I’m pretty new to UE4. Thanks!
