Elvis 2.2.0 : Input vs Insert mode

Question

We can start elvis in input mode using -i option. Also we can start input mode with various commands that specified in help :help.

But users call insert mode too which can also determined from h command :h. Is there any difference between insert mode and input mode in elvis?

Also consider that -i option is for startup command line: elvis -i which is specified in help: elvis --help

elvis version: 2.2.0

I think the insert and input modes are the same thing.

From the documentation you can see all the vim modes :

:h vim-modes

Vim has six BASIC modes:
Normal mode
Visual mode
Select mode
Insert mode
Command-line mode
Ex mode

There are six ADDITIONAL modes.  These are variants of the BASIC modes:
Operator-pending mode
Replace mode
Virtual Replace mode
Insert Normal mode
Insert Visual mode
Insert Select mode

There is no input mode here, it should be a second name for the insert mode

Also the -i flags doesn't seems to do what you say. The documentation says that the -i flag start vim another viminfo file. (see :h -i)

The flag you might want to see is the -y : it start vim in "easy" mode. (see :h -y)
