when run the command of helm-find-projectile-file, it will show a file lists in the mini buffer, and then I can use up and down key to select the file I want to view. But is it possible to view the file content when I select a file without press the "Enter" key? if press the Enter key, then I have to get back the helm session. I just want to use up and down key to go through each file, and then let emacs show the file content immediately.

You have to press C-j or C-zto see the content of the thing under the selection.

  • I am using spacemacs, ctrl+j just move the item down, just like key of down array.

  • Try C-z. It is helm-execute-presistent-action. I have updated my answer.

  • C-z pop up a HELM Action: It has a menu list, like [f1] Find file etc.

  • Add C-z or whatever key you want for helm-execute-persistent-action to helm-map first (define-key helm-map (kbd "C-z") 'helm-execute-persistent-action).

Try helm-follow-mode, it should do the trick.
