Improve Helm configuration
The current prelude-helm only uses a single command of Helm, which is a waste given how Helm contains many other commands. When prelude-helm is activated, users should be able to utilize all of these useful commands. If a user wants to use Helm, he will want to use all of its features anyway. prelude-helm is configured that it is able to be used with this [guide](http://tuhdo.github.io/helm-intro.html).

#### Helm
|
||||
|
||||
Helm is setup according to this guide: [A Package in a league of its own: Helm](http://tuhdo.github.io/helm-intro.html).
|
||||
|
||||
You can learn Helm usage and key bindings following the guide. <kbd>C-c h</kbd>
|
||||
is Prelude's default prefix key for Helm. If you don't remember any key binding,
|
||||
append <kbd>C-h</kbd> after <kbd>C-c h</kbd> for a list of key bindings in Helm.
|
||||
|
||||
#### Key-chords
|
||||
|
||||
**Key-chords are available only when the `prelude-key-chord` module has been enabled.**
