Client Keybinds

The keybinds in a modpack are always an unholy clusterfuck mess. Conflicts galor, and these conflicts often hide or break useful functionality in the mods you are using. I usually start by:

1. Copy options.txt from previous modpack (if available).
2. Unbind most modpack keybinds.

Leave any keybinds like Show Description set across the different mods. These show additional tooltip information.

I then update/tweak certain keybinds to get started.

Minecraft

These keybinds swap crouch and sprint because why the fuck are the defaults the way they are?! I also like to update the chat keybind to match WoW. Who wants to hit T every time they want to chat?

• • Sneak → Left Control
  • Sprint → Left Shift
  • Open Chat → Enter
  • Load Hotbar Activator → Not Bound
  • Save Hotbar Activator → Not Bound
  • Narrator → Not Bound

Gameplay Mods

Apotheosis

This mod adds all those named bosses to the world that drop crazy tiered gear. The Open World Tier Select keybind is pretty much mandatory or you won't be able to access the harder mobs with better loot.

• Compare Hovered Equipment → Left Shift
• Link Hovered Item to Chat → Shift + T
• Open World Tier Select → Ctrl + T

Applied Energistics 2

AE2 eventually becomes the main way to access your items. I like to use the R key to pull up the different wireless terminals since it is right next to inventory E keybind. Assign a numpad keybind for the magnet card if you plan on using that.

• Modifier for Mouse-Wheel Items → Left Shift
• Open Wireless Pattern Access Terminal → Shift + R
• Open Wireless Pattern Encoding Terminal → Ctrl + R
• Open Wireless Terminal → R
• Place Parts on Opposite Side → Left Shift

Iron Jetpacks

If included, this will be the easiest way to obtain early-game flight, so you'll use these hotkeys a lot. I actually just use the defaults here.

• Decrease Throttle → ,
• Increase Throttle → .
• Toggle Engine → V
• Toggle Hover Mode → H

Mekanism

The one and only, one of my favorite mods. The MekaSuit is one of the most power pieces of gear in the game and comes with a lot of toggle keybinds you'll find in the Numpad Toggles section. However, for the main-hand Atomic Disassembler or MekaTool, it helps to have a mouse button bound to change its modes.

• Item Mode Switch → Button 4

Sophisticated Backpacks

Most modpacks include these backpacks as a great way to expand your inventory. It has a number of keybinds but I usually just assign the main one.

• Open Backpack → B

Numpad Toggles

Many mods allow you to toggle gear and weapon features using keybinds. I like to use the numpad keys to toggle most of these passive abilities. Feel free to adjust these to whatever works best for you based on the mods available in the modpack.

• Applied Energistics 2 / Toggle Magnet Card → Keypad 4
• Artifacts / Toggle Night Vision Goggles → Keypad 9
• Artifacts / Toggle Universal Attractor → Keypad 3
• Mekanism / Chest Mode Switch → Keypad 5
• Mekanism / Feet Mode Switch → Keypad 1
• Mekanism / Head Mode Switch → Keypad 8
• Mekanism / Legs Mode Switch → Keypad 2
• Mekanism / Module Tweaker → Keypad /
• Mekanism / Show HUD → Keypad 0
• Simple Magnets / Toggle Magnet → Keypad 7

Interface Mods

FTB Chunks / Quests / Ultimine

FTB Chunks will be your go-to map in most modpacks. The quests and ultimine keybinds are also staples of most modpacks.

• Open Map → M
• Zoom In Minimap → Keypad +
• Zoom Out Minimap → Keypad -
• Open Quests → G
• FTB Ultimine → `

JEI

If EMI is not available in the pack, JEI will be the main way you search for items and recipes. If EMI is available, do not bind these.

• Add/Remove Bookmark → A
• Show Recipe → Left Button
• Show Uses → Right Button
• Close Recipes GUI → Escape
• Previous Recipe → Button 4

JourneyMap

Sometimes included alongside FTB Chunks, this map has more features but can be a pain to configure (why is the default map text so small on large screens?!).

• Show / Hide Fullscreen Map → J
• Zoom In → Keypad +
• Zoom Out → Keypad -

Utility Mods

Building Gadgets 2

Most modpacks include some sort of crafting utility like this mod. I like to assign whatever tool it is to Z for easy access while I build.

• Settings Menu → Z

Crafting on a Stick

This mod adds a bunch of different crafting tables on sticks that you can wear as curios. It puts its hotkey in the Inventory section hidden amongst the default Minecraft hotkeys.

• Open Crafting on a Stick → Shift + E
  

Crafting Tweaks

The Compress * keybinds in this modpack are super useful for quickly compressing items in your inventory to save space.

• Compress All → Shift + K
• Compress Item → Ctrl + K
• Compress Stack → K
  

GuideME / Ponder

These two keybinds are used by multiple mods to display in-depth guide information about a block you are hovering over. Its best to leave these bound to help you learn!

• Open Guide for Items → G
• Ponder → W

Inventory Tweaks (ReFoxed)

This keybind (or similar if provided by a different mod) is super helpful in keeping your inventory organized.

• Sort Inventory Under Cursor → Middle Button

Iris

The default hotkeys for working with the shaders in this mod are R, O and K. I don't like keybinds that toggle game features or trigger reloads without using modifier keys, so I add Alt to each of these.

• Reload Shaders → Alt + R
• Shaderpack Selection Screen → Alt + O
• Toggle Shaders → Alt + K

Just Zoom

This is sometimes provided by this mod or another mod. Its common to bind C to the camera zoom feature (a carry-over from Optifine, one of the first mods to add this feature).

• Zoom → C

More Overlays Updated

These keybinds make it easier to ensure complex machines stay within a single chunk and that your light levels are high enough to avoid monster spawns.

• Toggle Chunk Boundaries → F9
• Toggle Light Overlay → F7

TrashSlot

A quick keybind to delete items can be useful if you are trying to move fast. This will delete the item in your inventory under your cursor.

• Delete Item → X
