Similar to a different post, but different issue so I figured I'd make a new thread.
In normal mode, Ctrl+u and Ctrl+d do not scroll up/down by half pages. Instead, Ctrl+u falls back to u (undo) and Ctrl+d does something else (I honestly don't know what it's doing, but it's not scrolling).
(If we instead want to put these issues into a single thread, let me know. Wasn't sure the best way of doing this, but figured this would ensure the issue gets seen)
