Jump to the first word of the line (not a space)

  question, vim

In normal mode, entershift+^6Can be moved to the first non-blank space,
If it is in insert mode, I don’t want to switch to normal mode first. What input can jump directly to the first word of the line (not the space)?
The home key is no good, no, if the wardrobe is blank, my original intention is not to go to the blank space of the wardrobe, the non-blank space of the wardrobe!

Definitioninoremap ^ <Esc>^i. Press under insert mode^, you can move to the first word at the beginning of the line.
