I'm using Doom Emacs with treemacs inside it.

When I look through each source file from side tree, I need to press
Enter to open the file. How to view the file content without Enter but
just move the cursor in the tree menu?

Please try reading the documentation for the package before asking for
support.
What you're looking for is listed under the "Detailed Feature List":

Do you mean `Follow-mode`? I think, OP is after `treemacs-peek-mode`,
which does the opposite and is only mentioned in the "General
Keybinds" section.

I run `treemacs-follow-mode` from M-x, but it doesn't work.

`P` activates peek-mode, you can scroll the other window with `M-J/K`
from treemacs. Admittedly that feature is shown only in the helpful
hydra. I'll make sure it's added to the readme.
