Go to beginning of current word and simultanously switch into insert mode

Question

I know that there's I (in normal mode) which goes to the beginning of the line and goes into insert mode.

But does Vim have a built-in/default command to go to the beginning of the word my cursor is on and simultaneously switch into insert mode?

You can press bi or Bi. If you think the two keystrokes are too long.... you can create a mapping:

nnoremap  bi

Note that the above is just an example, you can replace it with the key you like.
