So I tried the following. Actually, you can pack on slide with space and then jump back at the beginning so that you build up speed, which I don't quite understand how it works. So I still think Perma-Sliding might be the best way and have been thinking how to do a multi-bind run in Classic 12, which is challenging since you need the keys W, A and S for the wallrun, which is essential. That's why I multi-bind another action, namely I put W on forward and W on right but put W on Slide as usual, which means that you always run diagonally right when you press W, as you can see on the keyboard overlay. Because you habe to choose one wall, right or left, so you dont really need the other side so you can put A or D to move forward. Nevertheless, Perma-Sliding is still possible this way and is therefore much more effective, but Manual LRF is no available when you do this
