pub fn try_parse_binding(binding: &str) -> Result<Vec<KeyChord>, ParseKeyError>Expand description
Parse a whitespace-separated chord sequence, returning ParseKeyError on
the first unrecognised token (or if the string has no tokens).
Use this when binding from a user-editable config or a remap UI so a typo
like "ctrl+shft+x" is reported instead of silently ignored.
