`Delete` key doesn’t work on vim insert mode for deleting previously typed content

vim

I opened vim in my iterm2. Firstly, I typed something on insert mode, like

Hello

At this stage, if I didn't exit from insert mode, delete key works and can delete the whole word if I want.

If I quit insert mode, and open insert mode again, this Hello can't be removed by delete key. But the newly typed-in content can be removed.

I've renamed my .vimrc, problem still exits.

In the shell command-line, my delete key works well.

And I did some test on remote server through iterm, didn't encounter the same issue.

What could be the cause of this problem? How to fix it?

PS:
As I'm using macbook, the delete key is corresponding for backspace in PC.

Just put this to your .vimrc :

set backspace=indent,eol,start

Vim shortcuts in insert mode

End (1 key) the only suggestion that has fewer keystrokes than
Esc A (2 keys + use of shift), the one you have suggested.
Ctrl-o $ OR Ctrl-o A (2 keys + control and shift), the most keystrokes yet.

The last one illustrates the use of Ctrl-o in Insert mode, which lets you interrupt insert mode to use exactly one normal mode command before returning.

Vim insert mode completion for sentences

Try C-x C-u. You will need to define the completion as described in the complete-functions section of the vim help. Type:

:help complete-functions

To see this section. Similarly,

:help i_^X

(where ^X is the C-x character) will show you the section that describes this mode. Keep in mind that sentences typically end with the pattern /. /. Good luck.
