How to collapse / expand all comment blocks in a file in PhpStorm?

Question

In PhpStorm, what is a quick way to collapse or expand all comment blocks (docs) in a file?

The docs here say:

Folding and expanding code blocks works for entire classes, inner and
anonymous classes, method bodies, import lists, comments, HTML and XML tags,
closures and language injections.

And further down says:

If you hold the Alt modifier and click a toggle button in the gutter, the code block
will be collapsed or expanded recursively, ie all sub-blocks within the parent 
block will also be collapsed or expanded.

But I do not see how this one works Alt modifer? I hold Alt, then press the toggle button, and only this block crashes once. I tried this in the doc block of the upper class, as well as in the doc blocks of the properties / methods. Did I miss something?

Code | Folding | Collapse / Expand doc comments

By default, it does not have a shortcut, but you can easily add it to Settings (Preferences on Mac) | Appearance and behavior | Keymap is any shortcut you want.
