The '''debug screen''', '''debug overlay''' or '''F3 screen''' functions as a menu for accessing debugging information, but it also provides useful in-game information like [[Minecraft:Coordinates\|player coordinates]]. It is triggered when {{key\|F3}} is pressed.

	The debug screen consists of info text lines and ~~five~~ toggleable graphs: profiler, frame rate, [[Minecraft:tick]] rate, bandwidth, ~~and~~ [[Minecraft:w:Lag (video games)#Ping time\|ping time]] graphs.		The debug screen consists of info text lines and six toggleable graphs: profiler, frame rate, [[Minecraft:tick]] rate, bandwidth, [[Minecraft:w:Lag (video games)#Ping time\|ping time]], and lightmap graphs.
