Pro Vimtutor teaches the basics of Vim in 30 minutes
Vimtutor is an excellent interactive tutorial for people with no prior experience of Vim. It's bundled with Vim and takes about 30 minutes to complete.
Pro Everything is a mnemonic
Vim associates keys with words. For example,
d is for "delete" and
w is for "word". To perform an action you string together letters. Thus, to delete a word, press dw.
This way it's possible to abstract a large amount of functionality that Vim provides in an intuitive way.
Pro Enables effective keyboard-driven editing due to its modal nature
Interaction with Vim is centered around several modes. Each mode has a different purpose and switching between them changes behaviour and keybindings. There are 12 modes in total (six basic modes and six variations on basic modes) and four of them are used commonly.
Insert mode is for entering text. This mode most resembles traditional text entry in most editors.
Normal mode (the default) is entered by hitting ESC and converts all keybindings to center around movement within the file, search, pane selection, etc.
Command mode is entered by hitting ":" in Normal mode and allows you to execute Vim commands and scripts similar in fashion to a shell.
Visual mode is for selecting lines, blocks, and characters of code.
Modes allow separating concerns between various tasks and reusing keys for different kinds of functionality. As a result, the workflow becomes more efficient.
