Here is the list of the possible annotations on level maps saved with Ctrl+Shift+F12 or --screenshot-level-extras.

Items marked with [!] can't be found on the original levels.

* Floors:
	* white "~~~~": Regular loose floor.
	* purple "~~~~": Stable loose floor: It can't be broken by the prince, only by another loose floor or a door event. [!]
	* green "^^^^": Opener / raise button.
	* red "vvvv": Closer / drop button.
* Traps:
	* green "safe": Spikes which won't hurt the prince. [!]
	* green or red "stuck": Stuck chomper. [!]
* Potions:
	* grey "x": empty [!]
	* red "+1": heal
	* red "+++": life (extra HP)
	* green "slow fall": slow-fall / feather fall
	* green "flip": flips the screen upside-down
	* blue "-1": hurt / poison
	* blue "trig": trigger / open
		* A yellow "blue trig" shows which tile is triggered. (Only if there is such a potion in the reachable rooms.)
	* white number: Some other kind of potion. [!]
* Door events:
	Yellow numbers show:
		1. what events are triggered by a button,
		2. what events point to a tile.
	In both cases, the same tile can have multiple numbers.
	Case 2 shows only those events which can be triggered from the reachable rooms.
* Teleports:
	Each teleport has a yellow number. The teleport takes the player to the other teleport with the same number.
* Guards:
	yellow "s5 h4": The first number is the skill, the second is the number of hit points.
	Guard skills are documented in default_skill_options.txt and here: https://www.popot.org/documentation.php?doc=PoP1GuardTypes
* Special events: (in yellow)
	You can find more information about them here: https://www.popot.org/documentation.php?doc=PoP1SpecialEvents
	Note: Since version 1.23, SDLPoP recognizes if certain events were placed elsewhere by a mod.
		This works only with events whose place can be customized.
	* level 0:
		* "exit": Complete the level by entering this room.
	* level 1:
		* "start trig": This tile is triggered (pressed) when the level starts.
	* level 3:
		* "<- chk point": The checkpoint is activated by leaving the room this way.
		* "check point": The prince restarts here if the checkpoint was activated.
		* "removed": This tile is removed when you restart at the checkpoint.
		* "loud": The closing sounds of this gate can be heard in all rooms.
		* "skel wake": This skeleton will wake if the exit is open.
		* "skel cont": If a skeleton falls into this room, it will be placed here.
	* level 4:
		* "mirror": The mirror appears here when the exit is open.
	* level 5:
		* "stolen": This potion will be stolen by the shadow.
	* level 6:
		* "exit down": Complete the level by leaving the room this way.
	* level 8:
		* "mouse": The mouse will appear here if the exit is open.
	* level 12:
		* "disapp": This sword will disappear.
		* "disapp ->": The sword will disappear when you leave the room this way.
		* "floor": Floors appear here.
		* "exit": Complete the level by entering this room.
	* level 13:
		* "fall": These loose floors fall if you're in the room below them.
		* "meet ->": Jaffar's music is played when you leave the room this way.
		* "Jffr trig": This tile is triggered when you enter any room from the right after Jaffar died.
	* level 14:
		* "end": You win the game by entering this room.
* Starting position: Yellow "start" with an arrow showing the starting direction.
	* This can be useful on level 7 or 13 where the prince starts off-screen
		and thus he is not visible on the map if you made it from the command line.
* Broken room links: White number on red background on the corresponding edge of the room. [!]
	Note that such levels usually appear incorrectly. Consider yourself lucky if they don't fall apart on the map. :)
	In the worst cases you get errors on the console: "Warning: room XX was mapped to the same place as room YY!"
		SDLPoP puts such rooms to the bottom of the map since version 1.19.
	Sometimes you can get a better map if you make the map manually from some room other than the starting room.
* Room numbers: White number on grey background in the top-left corner.
