He guys,

I can't get the walk key to work in V1.23. The last time I had it working was in 1.21. (see capture)

I do my own manual editing of the xml files.

If anyone figures out how to get it working again in v1.23 please post it here. Even a screenshot of the modified xml file, like the one I attached with edits that worked before v1.23, would be appreciated

UPDATE

I did figure out how to add a simple walk forward keybind. It's not a modifier but just a seperate walk forward key so it doesn't effect any of the other directional keys.

I just added a second move forward line with a lower speed and bound it to E. (.4 instead of 1.0) See capture2

That's a great find. I think I will configure one button as 2x sprinting speed. Especially in the city centre walking mid-length distances is often less of a hassle than driving, but it's still slightly too slow. A "turbo-run" would be nice.

But if the old method doesn't work in 1.23 that could indicate they are working on something related to key binding and there might be some changes in the next update.
