  #### handleKeys
  * Allows user to select certain modifier keybindings and delegate them back to VSCode so that VSCodeVim does not process them.
  + * Complete list of keys that can be delegated back to VSCode can be found in our [package.json](https://github.com/VSCodeVim/Vim/blob/master/package.json#L44). Each key that has a vim.use<C-...> in the when argument can be delegated back to vscode by doing "<C-...>":false.
  * An example would be if a user wanted to continue to use ctrl + f for find, but wants to have useCtrlKeys set to true so that other vim bindings work.
