The last operator given in Normal mode. This is a single

Operator-pending mode and then use the operator, e.g.: >vim

The value remains set until another operator is entered, thus

v:operator is not set for |:delete|, |:yank| or other Ex

Read-only.

See also |serverstart()| |serverstop()|.

$NVIM is set by |terminal| and |jobstart()|, and is thus
a hint that the current environment is a subprocess of Nvim.

Result of the last shell command. When non-zero, the last

Normal mode command to be executed after a file has been
