Your rogue isn't moving because he doesn't have Click to Move enabled when you pass him the IWT key.

You don't need to have G->4 set in a second step, you can put that in the same step. All you need is Click to Move to be on.

The reason Click to Move (CTM) turns off is because the standard IWT Mapped Key in the General key map, which you are using, turns CTM on in step 1, and back off in step 2. That's because most people play with CTM off. You can just remove the Action from Step 2 of Interact with Target in the General key map, making it an empty Step, if you want. If you remove that Step entirely, change the "execute a Step when the Hotkey is _______" option to just "pressed" or just "released" instead of "pressed OR released".
