pub const DEFAULT_LEADER: &str = "<Space>";Expand description
OM.2b: what <leader> expands to unless the host sets otherwise.
<Space> rather than vim’s historical \\. Vim’s default is an artifact of
\\ being one of the few unbound keys in 1991; the modern vim world
overwhelmingly maps leader to space, and nvim-orgmode’s documented bindings
assume it. Convention beats historical accuracy on a surface this
muscle-memory-bound (the standing “UX follows convention” rule).
