I've been adding Ctrl+B (PgUp), Ctrl+F (PgDn), Ctrl+D (half PgDn) and maybe Ctrl+U (half PgUp) Vim-like shortcuts, but recently that stopped working on IR v4 (Anki 2.1b20).
This has been working for some time, but at least right now, Ctrl+B does not work (the key combination, no matter how I use it). Maybe it is used elsewhere.

Doesn't work with 4.7.5 + 1 commit and newer:
It still works on 3.8.2 (Anki 2.0.x)
