Enable prelude-global-helm-global-mode by default
Since Helm is another option to Ido, users who want to use it fully should benefit from the default Prelude setup. If some users don't like, they can always disable global Helm mode according to the instructions in the homepage. User can enable Helm everywhere with prelude-helm-everywhere. This change also enables Helm version of command history in shell and eshell. It also adds minibuffer history without overrides any key binding in minibuffer-local-map.

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.

By default, Helm won't activate these global key bindings, so you can use Helm along with Ido and Prelude's default commands:
|
||||
If you love Helm and want to use Helm globally with enhanced `helm-find-files`, `helm-buffer-lists`..., you will have to also add `(require 'prelude-helm-everywhere)`.

When `prelude-helm-everywhere` is activated, Helm enables these global key bindings:

If you prefer Ido in everywhere, you should not add `prelude-helm-everywhere`, so you can use Helm along with Ido and Prelude's default commands.
|
||||
|
||||
You can always reactivate Helm with `(prelude-global-helm-global-mode-on)`.
|
||||
|
||||
You can use above key bindings by putting `(prelude-global-helm-global-mode +1)` right after `(require 'prelude-helm)`. If you enable
|
||||
these key bindings, you should not enable `prelude-ido`.
