Default key bindings in FTB packs - as you can see, some of them overlap, and some of them appear not to work. These are all from the config files, so to fix conflicts for mods that don't have a GUI for editing bindings, edit the config file and use http://www.minecraftwiki.net/wiki/Key_codes as a reference.
Hats Mod
V = Hat menu
EE3
C = Extra
G = Toggle
R = Release
V = Charge
NEI
[Backspace] = Back
L = Recipe List
O = Hide
P = Potion
R = Recipe
U = Usage
X = Enchant
[F7] = Mob Spawn Overlay
[F9] = Chunk Overlay
[PgDn] = Next
[PgUp] = Previous
Portal Gun
G = Grab
R = Reset
[Left Click] = Shoot portal
[Right Click] = Shoot portal
[Middle Click] - Zoom
VoxelMap
- = Create Waypoint
= = Menu
] = Large map
[ = Toggle Mobs
/ = Zoom
Inventory Tweaks
R = Sort Inventory
[Space] = Transfer everything from target inventory
IC2
[Left Control] - Boost, does not work by default as it conflicts with "Placement Modifier" binding so change one of them in Options->Controls.
OK that's all I have so far. Most of this is from searching the configs for the word "bind". If anyone knows of any more key bindings, especially if they're different from the mod's default binsings, then let me know and I'll update the list. I discovered something doing this - I never knew about the Portal Gun zoom!
