Answer 1

If you are anywhere on that line, you can try this:

• 0 - to go to the beginign of line
• /one - to jump to the word one (in this particular case even fo would be enough - see :help f)
• ct_ - this will delete everything between cursor and character pressed after t - so in this case everything till _ - and since we used c it will leave you in insert mode - see :help t

Answer 2

Another alternative is to use vim-textobj-variable-segment which along with vim-textobj-user, will allow you to edit segments in snakecase and camelcase words. It provides iv and av text objects. This would allow you to do fociv to change you one in your example.
