Also, you can view most if not all of them here: [[Commands]]. I just tried to put some details in mine.
That said, let's go through the most important keys. These are the keys that's function might be unknown, or have some useful aspects that aren't commonly known/are often forgotten. They are organized in the same order as the keyboard layout descriptions in the game.
'''*Please message me in the forums If I get any key wrong, or I missed some vastly game changing key changing game*'''
'''Home and End''' (Located in the top right corner of the keyboard), '''Page Up and Page Down''' (Located in the bottom right corner of the keyboard): These keys allow you to move diagonally. Homes moves you up and left, End moves you down and left, Page Up is up and right, and Page Down is down and right. Importantly, it's counted as a single move. Even more importantly, it allows you to interact with otherwise non-interactable objects, most notably being 2 of [[Haathbar]]'s bookshelf. '''MOST IMPORTANTLY''', and I cannot stress this enough because it makes your run so much safer, being at a diagonal greatly decreases damage from certain entities, including trapped door explosions, zaps from [[Wand of Fireballs]] and [[Wand of Lightning]], and the [[Enner Beast]] scream.
'''''Source Code Fact''''': Alternatively, you can use the keys 789uiojkl keys for movement (the directions being rather easy to figure out), which is good if you want to have all your movement in a single area. On a larger keyboard, the numpad can also be used for movement.
'''a.''': ApplyWait. The gameSimilar to 's interaction with wands'earch, tools, and certain miscellaneous items (chests, traps, and keys). With wands, 'but takes a' will not zap turn rather than a wand and instead break, releasing all their stored energy onto the user, namely youtick. This is most Could be useful for the wand of teleportation, but is also applicable with the wand of cloning and mirroring. Careful with offensive wands and prepare good resistance or good armor, as they hit you the hardest in their explosion radius. Apply can also be used with traps to activate them on the spot you are standing on. Do not activate a backpack of gunpowder without a very good reason, as it will instantly detonate on you. Can rather niche use with magical items or keys to activate their abilities or open chests and doors, respectively. FinallyStill, use 'A' (capitalized) scroll down to repeat look at the last 'a'pply action, which can save time. '''C''': Chat. What is used to sci-talk with various entities, but also to find some interesting lore. Holding down 'Cs' will let you chat to the entity you previously talked earch button to, as long as they are still in the 1 block radius, very good for when surrounded by multiple creatures. '''c''': Close. Closes doors. More see how useful that one would think, as only closed doors can be locked. Good for fleeing and gaining time. '''!''': Dip. A supremely useful tool that enables a player to transfer liquids from one container to another. Given that cans cannot break, it's a prime target for moving healing liquids into. On the other hand, dousing flames requires only a tiny bit of liquid, so moving liquids to vials to cover your flaming scrolls in is sufficient to quickly extinguish the flames while saving much liquid. '''d''': Drop. Self-explanatory, should be frequently used later on to not be burden or stressed.
'''g''': Go. Allows a player to quickly traverse terrain. I suppose if you want to speedrun IVAN, this is the key to keep track of. The way it works is after pressing g, you can choose a direction (including diagonals!) to continuously run in until you
These make sure that you won't take dumb damage while running, but be careful, as using 'g' too much will often lead to running unintentionally into traps or get the player too close to potentially lethal enemies. If you have ESP, use it to the fullest before you run ahead.
'''Ld''': lookDrop. Also selfSelf-explanatory, but people need should be frequently used later on to not be burden or stressed. It is also good to do it moreleave your important scrolls and some backup wands in other floors so they won't go up in flames at the first trap you meet. '''t''': Throw. If Throw an item. Very strong if you have the whole map unlocked, instead plenty of running around looking for the way up or downweapons to throw, just look to remember places you've been to beforeparticularly daggers and short swords early game, saving time and energypoisons and magical weapons late game. Throwing ability is based on arm strength though, literallyso don't expect that adamantium halberd to go too far. You can Throwing wands will also see enemy equipment to make decisions about before fights by 'L'ooking at often break them and using certain keys, or what items are on a faraway block that you can see.
'''Oa''': OfferApply. When standing on an alterThe game's interaction with wands, tools, and certain miscellaneous items (chests, traps, and keys). With wands, 'a' will not zap a wand and instead break, releasing all their stored energy onto the user, namely you. This is most useful for the wand of teleportation, but is also applicable with the wand of cloning and mirroring.

Better Can use with magical items make gods happieror keys to activate their abilities or open chests and doors, or items associated with them respectively. Finally, use 'A' (like lanterns for [[Legifer]]capitalized) to repeat the last 'a'pply action, very useful)which can save time. You can see who is associated with what in [[List of Material Values]]
'''pz''': See gods sectionsZap, use a wand in a certain direction. Most common form of wand use.
'''r''': Read. Uses scrolls, just so you know.
'''he''': RestEat. Allows See nutrition '''D''': Drink. Consumes liquids. Some food that seem like you eat them are actually liquids, such as chicken soup and pea soup, so you might have a bit more food than you think. '''C''': Chat. What is used to sci-talk with various entities, but also to find some interesting lore. Holding down 'C' will let you chat to the player entity you previously talked to heal up while staying , as long as they are still in one placethe 1 block radius, very fastgood for when surrounded by multiple creatures. '''T''': Taste. In a similar fashion to dip, taste allows you to consume only a small portion of one container. Still takes This makes potions of healing several times more effective especially in the early game time though, but later on when your health increases with your [[Endurance]], drinking the whole potion is fine. '''!''': Dip. Also note A supremely useful tool that enables a player heals twice to transfer liquids from one container to another. Given that cans cannot break, it's a prime target for moving healing liquids into. On the other hand, dousing flames requires only a tiny bit of liquid, so moving liquids to vials to cover your flaming scrolls in is sufficient to quickly extinguish the flames while saving much liquid. '''c''': Close. Closes doors. More useful that one would think, as fast on only closed doors can be locked. Good for fleeing and gaining time. Many early game enemies will lose track of you if you r'u'n around a couch corner and close a whooping five times as fast on a beddoor behind you.
'''s''': Search. Top tier key that makes the player check their surroundings (a one block radius) for traps. The trap checking, while useful, is not the main benefit from searching, but instead the singular tick a search takes. For reference, IVAN is split into turns, with each turn having 10 ticks. Every entity in the game can only move so many ticks per turn, which is improved by agility. Since entities usually move at the same tick each turn, This can be somewhat exploited by the search key, as staying slightly far enough enables players to stay just out of range, search til an enemy moves in, attack them, and run to the next block. This method, known as kiting, is enough to kill most enemies in the game with enough time, though it falter against spellcasters or a certain queen.
'''.l''': Waitlook (with a lowercase l). Similar Also self-explanatory, but people need to searchdo it more. If you have the whole map unlocked, instead of running around looking for the way up or down, but takes just look to remember places you've been to before, saving time and energy, literally. You can also see enemy equipment to make decisions about before fights by 'l'ooking at them and using certain keys, or what items are on a turn rather than faraway block that you can see. '''I''': issue commands (with a tickcapital i). Could be Very usefuland '''instantaneous''' command that enables a player to order allies around. The functions of who to command are relatively self-explanatory, but rather niche useyou can make allies run away, stop following you, prevent them from changing equipment, and enable them to consume valuable items. With proper managing of your team, you can effectively move your allies around to better synchronize their attacks. '''O''': Offer. When standing on an alter, you can offer items to the god of that alter. Better items make gods happier, or items associated with them (like lanterns for [[Legifer]], very useful).You can see who is associated with what in [[List of Material Values]]
'''tp''': ThrowSee gods sections. Throw an item '''h''': Rest. Very strong if you have plenty of weapons Allows the player to throwheal up while staying in one place, particularly daggers very fast. Still takes in game time though. Also note that a player heals twice as fast on a couch and short swords early a whooping five times as fast on a bed. '''k''': Kick. Kicks stuff. While the damage from kicks falls off very quickly as the gamecontinues due to the lack of damage, kicks can be used to knock enemies back in desperate situations, bust open locked doors (be careful that they aren't trapped), and poisons and magical weapons late gameopen locked chests. Throwing ability is based on arm If you have the strength thoughto kick a chest at least a block, so don't expect that adamantium halberd you can kick the chest up to go too farand then against the wall, which greatly increases the changes of breaking the lock. Throwing wands will also often break themThis is particularly useful for the meteoric steel chest in the not so secret secret room.
'''V''': Vomit. Removes some nutrients from your body in the form of a short range projectile vomit. Does poison enemies, but don't use this as a weapon unless you're at death's door with no options. Vomiting is mainly for getting rid of tape worms that can infest your body when you eat rotten food.
'''z''': Zap, use a wand in a certain direction. Most common form of wand use.
