The following is only for Vim, not for vi. 12 species in total. The six basic modes are as follows:

• Normal Mode
• Visual Mode
• Select mode
• Insert Mode
• Command line mode
• ex mode

See:help vim-modesfor details.

Remember that in vi, the function similar to Vim's normal mode is called "command mode", the function similar to Vim's command line mode is called "last line mode", and the function similar to Vim's insert mode is called "edit mode".
