Internal Program Version: vim  9.1.0512

Vim (Vi IMproved) is an almost compatible version of the UNIX editor
vi. Almost every possible command can be performed using only ASCII
characters. Only the 'Q' command is missing (you do not need it). Many
new features have been added: multilevel undo, command line history,
file name completion, block operations, and editing of binary data.
