I'm using the newest build of Sandbox on a very old laptop. System specs aren't needed here anyway.
#1. How to I change the controls for the Middle Mouse Button and Scroll wheel? In the FAQ it says this can be done through the Options menu, but this, as far as I can tell, is not true. It was also mentioned that I could alter the default config file. Well that's not working either. I would like to use [ ] \ for Mouse Wheel Up (I believe this is called MOUSE4), Mouse Wheel Down (MOUSE 5) and Middle Mouse Button or Mouse Wheel Button (MOUSE3), respectively. Alternatively I can try R T and F, since this puts these next to G which you use the MMB with. How exactly do I do this? I replaced the entries in default.cfg and nothing works

#2. For my first map I want to play with the grid sizes. So I need to fix problem #1 obviously before I can proceed. In this I will use different grid sizes with the character, and in comparison, exporting the blocks to Wings 3D and Hexagon. I want to configure both modelers so their units match Sandbox's, and I want to determine the grid size units that stack up to 5 or 6 for player height. Also going to figure out stair height. May make a video tutorial on this. But the problem is when I press E to enter Edit Mode I get a flying superhereo character. Which is cool, certainly, but I need a character standing on the ground. So how to I switch characters?
#3. Finally for my last issue I overwrote somehow the original village map. Do I have to re-install to restore this? I typed in the name in the Save Map As dialogue and everything. But it still messed it up

Hey thanks for your help! Sandbox is looking really cool and I think you guys have done an awesome job! I will be a good boy and search some more for answers. But tonight I hear my bed calling and I can barely focus so I think its time for sleep.
