Search for help information for different modes in VIM

There are several modes of vim, such as normal (normal mode), insert (insert mode), command line Mode, visual (visual mode). The same commands and shortcut keys function differently in different modes, so help information is also sub-modal.

Give me a chestnut:

What are the available values for BACKSAPCE when I want to see the set backspace?

If you're using: Help BACKSPACE, you can't find the answer, because here's how to find helpful information in normal mode

Use: Help ' backspace ', or use: Help backspace? , you will find the answer as it is, as this is the information for finding the operation settings.

Specific commands to use: Help helps yourself to see
