Map more weapons from the wheel to keys

Try GlovePIE

It's a program that's actually used to map things like MIDI controllers, Wii-motes and PS3 controllers to actual keyboard commands, but naturally also works with regular keyboard remapping!

Note: It looks scary when you run it, but under View you can set it to GUI. There you can set it to Manual and change your Output Device to Keyboard. Then you just remap the regular 1-0 with your Numpad version.

Here's how the help file describes it:

Start up PIE. Choose the "File" Menu, then click "New". This will clear whatever was in the big white box so you can type your own script. We want the W key to be controlled by the up key so type this on one line then press Enter:

W = Up

This is a working PIE Script so you can test it by choosing the "Run!" menu and clicking "Run".

Whenever you press the up arrow key (on the cursor pad, not the numeric keypad) it will type a "w". Try it out! This will work in any program. Note that it will still move the cursor up. The Up arrow key still has its original function, but it emulates a w at the same time. Try holding down shift and pressing Up. It will type a capital W, unless capslock is on. Unlike the real "W" key, holding down the Up arrow will only type a single "w".

Now chose the "Run!" menu and click "Stop". This will return our keyboard to normal.

Now do the other keys like this:

A = Left S = Down D = Right

(Don't worry if the S is orange, that is because S is also an abbreviation for seconds).

Save your script as Tutorial1.PIE by chosing the "File" menu then "Save As...". And run it again. Stop it when you have finished playing.

As far as I know, there's no way to remap the keys outside of a recompiling from source, or a crazy hack like using AutoHotKey to map entirely different keys on the keyboard to hjkl/yubn. Obviously that has side-effects though.

So you have a couple of options:

1. You may not have an actual numpad, but most laptops have a mode that can "convert" part of the keyboard into a numpad, by holding down the "Fn" key, or using a "Fn Lock" key to toggle it on/off.
2. Get used to hjkl/yubn, and be glad that if you ever decide to learn how to use vim in the future, you'll already have moving around with hjkl solidly ingrained into your muscle memory.
