Vim

• vi is created by Bill Joy, who later co-founded Sun Microsystems.
• vi stands for “visual”. Before that there was only line-editor.
• vi is part of POSIX standard.
• On most systems, vi is linked to vim.
• See NeoVim.
• In traditional vi, normal and command mode are called command and ex mode instead.

Tricks

• Run mess (= messages) to see what happened if plugin is not working.
• Use modeline for per-file config.
• s/xxx/xxx/gc, use c flag for confirmation.
• Use :r to read a whole file into current buffer
