Sets a global mapping for the given mode.

To set a buffer-local mapping, use nvim_buf_set_keymap().

Unlike :map, leading/trailing whitespace is accepted as part of the {lhs} or {rhs}. Empty {rhs} is <Nop>. keycodes are replaced as usual.

Example: >vim call nvim_set_keymap('n', ' ', '', {'nowait': v:true}) <

is equivalent to: >vim nmap <nowait> <Space><NL> <Nop> <

Parameters:

• {mode} Mode short-name (map command prefix: "n", "i", "v", "x", …) or "!" for :map!, or empty string for :map.
• {lhs} Left-hand-side {lhs} of the mapping.
• {rhs} Right-hand-side {rhs} of the mapping.
• {opts} Optional parameters map: Accepts all :map-arguments as keys except <buffer>, values are booleans (default false). Also: - "noremap" non-recursive mapping :noremap - "desc" human-readable description. - "callback" Lua function called when the mapping is executed. - "replace_keycodes" (boolean) When "expr" is true, replace keycodes in the resulting string (see nvim_replace_termcodes()). Returning nil from the Lua "callback" is equivalent to returning an empty string.
