+''vim'' is a modal editor (improving on vi). It can run without graphics, is ubiquitous, powerful, and efficient but is an acquired skill.
+  * **MIT's "missing semester" has an excellent summary of vim functions [[https://missing.csail.mit.edu/2020/editors/|video and notes]].**
+Vim’s design is based on the idea that a lot of programmer time is spent reading, navigating, and making small edits, as opposed to writing long streams of text. For this reason, Vim has multiple operating modes.
+  - Normal: for moving around a file and making edits
+  - Insert: for inserting text
+  - Replace: for replacing text
+  - Visual (plain, line, or block): for selecting blocks of text
+  - Command-line: for running a command
   * ''vimtutor'' is a program included with vim that will guide you through usage -- run it from the command line.
