NL 12.04
On first start, player offers two key mappings, functional and traditional. In functional, RMB (right mouse button) selects walker.
RMB should be hold-to-scroll instead.
Ideally, RMB is also select-walker, but that is far less interesting. With the questionable design where function-to-key bindings must be injective, anything else can be select-walker, I don't care much, I've bound Left Control for select walker but never use it.
