I really like how the less pager uses w to scroll up and z to scroll down since they are single keys, in vim I have to use CTRL+d/CTRL+f to get the same effect. Having to hold ctrl is a bit of a nuisance.
Of course I could just remap the scroll keys, but that might break plugins, generate bad karma, etc, etc...
Is there a single key shortcut to move down by a screen already? Your suggestions?
