If you want to use different mappings, map your keys to the
<Plug>CamelCaseMotion_? mapping targets your vimrc).

You can also disable all default mappings and only define the ones you want
setting the `g:camelcasemotion_map_keys` variable to `0`: (Default: `1`)

```vim
let g:camelcasemotion_map_keys = 0
```

EXAMPLE: Map to w, b and e mappings:

" To create a text motion, a mapping for operator-pending mode needs to be
" defined. This mapping should move the cursor according to the implemented
" motion, or mark the covered text via a visual selection. As inner text motions
" need to mark both to the left and right of the cursor position, the visual
" selection needs to be used.

" Vim's built-in inner text objects also work in visual mode; they have
" different behavior depending on whether visual mode has just been entered or
" whether text has already been selected.
" We deviate from that and always override the existing selection.
