I would love to be able to control my characters movement speed by using the mouse wheel. Would anyone else be interested in this mod? Any modders interested in making it?

I think thats actually quite a brilliant idea. Take this as a modest bump.

I too want to put my bid in for this to be made into a mod.

Well it will require CK because it scripting by nature
perhaps if vanilla scripting system allow we can use DX scancodes to detect mouse wheel movement and change character movement speed variable accordingly, if there no such function need to wait for SKSE, or we can is player sprinting to modify movement speed as well bind it to maximum Stamina as representation of Character Speed Attribute.

I cant remember the game now (maybe Gothic...) but having mouse wheel control running speed is something i have been in favour of for ages and never is in games.

Amazes me as anolouge movement is a big part of immersion in RPGs for me and is the sole reason i use a gamepad in Skyrim (that and relaxing on my sofa ofcourse...)

That would be ingenious.
I would not want to sacrifice my control over the third person camera just to get this, so one of these effects would need a modifier key. I think giving the third person camera a modifier key would make most sense.

I like this idea. Hope it can be done!

Another vote for this great idea.

That would be nice as I don't ever play in third person. Though I think I'd prefer wheelup to scroll through the favorites with the left hand, and wheeldown for the right. Doubt that's doable though. Having only 8 hotkeys gets annoying as a caster.
