I'm trying to add some console commands to the config files, so I don't need to type them every time I start the game. I'm using the GOG version, adding the Unnoficial Patch 11.5 basic.

Specifically, it'as some tweak to movement speed:

sv_runscale 0.7
sv_walkscale 4.0
sv_friction 7

However, I tried adding it to autoexec.cfg and user.cfg, but it doesn't work (config.cfg is not useful because it gets overwritten every time). I tried with and without quotes (sv_runscale "0.7"), doesn't work both ways.

I added another tweak to user.cfg (to bind Shift to toggle walk/run) and it worked, so I would expect that this is the file to tweak.

I'm also trying to tweak some hotkeys, and I see that the syntaxe is different. In user.cfg they work without quotes (e.g. bind SHIFT walk) and in config.cgf/default.cfg, it appears with quotes (bind "SHIFT" "walk").
