In order to specify underscores as Vim word boundaries when using vim mode in either bash or zsh, you can set the iskeyword option in your .vimrc file. This option takes a list of characters that Vim should consider as word boundaries. To add underscores to this list, add the character _ to the list. For example, to set underscores as word boundaries, you can add the following line to your .vimrc file:
set iskeyword+=_
Once this option is set, pressing the w key while the cursor is on the underscore in the example you provided will move the cursor to the w of "word".
