Like many others, I use the mouse left-handed, and remap movement & other keys to the number pad. Skyrim does not allow this, as NumPad 1-8 are reserved keys. After a lot of digging around, I figured out how to use these keys, without using a third-party program.

Warning - this requires some editing. You will need a hex editor program. (I used this one - http://www.chmaas.handshake.de/delphi/freeware/xvi32/xvi32.htm)

1. Make a backup copy of \Steam\steamapps\common\skyrim\Data\Skyrim - Interface.bsa, and then open the original with a hex editor. You should be able to see text/chars in the side window.

2. Scroll way, way down, to about address 34,701,270 (or search for "// Main Gameplay". You will see a bunch of text, that cleaned up, looks something like the code snippet below. The 1st column is the game event, the 2nd column refers to keyboard key ID's, the 3rd to Mouse button ID's, and the 4th to Gamepad button ID's. Notice that Hotkey 1 has keyboard key ID's of "0x02, 0x4f". After many hours of researching scan codes & hex unicodes, I know that this refers to "1" and "NumPad 1" respectively.

3. Edit out the 2nd part of every hotkey 2nd column entry. For example, change Hotkey 1 from "0x02,0x4f" to "0x02". (When I looked at the raw hex data for other entries, there were 4 "09" entries between the 2nd & 3rd data sets, so I made sure to keep the same when I edited these).

4. Save the file, and start Skyrim. You may now bind your numpad keys (just got back in game, and I now use Num5 for Forward, Num2 for Back, Num1 & 3 for strafing left/right).

I do not know what effect this will have on other key usage choices.

Enjoy!

Not to be an ass, but I believe I have an easier fix posted;)

Nice work, both of you!

Nice one. I recognize the layout of that, as it's what I was staring at for a long time. You beat my post by about an hour, too. Although, if you remove the 2nd set as I mention, the numpad 1-8 keys will no longer be reserved for the hotkeys.

The link, above, to the other fix thread is dead... what happened to it?

One of the mods "organized" the keybind threads.. well, most of them. They're mostly in one thread now:

http://www.gamesas.com/index.php?/topic/1261029-keybinding-issues-2-hotkeys-numpad-cannot-drop-cannot-take-books-cannot-spend-dragon-souls-etc/page__st__100

At least until they do another mass combine of threads.

My big problem is that they didn't leave any links behind, everything just "disappeared."

Please use one thread for all keybinding bug reports and fixes: http://www.gamesas.com/index.php?/topic/1261029-keybinding-issues-2-hotkeys-favorites-numpad-cannot-drop-cannot-take-books-cannot-spend-dragon-souls-etc/

Thank you.
