Intellij, project navigation. Expand all folder and file tree

Now, you can expand the entire directory structure in IntelliJ. All you need to do is to select the project in project explorer and hold Right Arrow button. It will expand all the files in that project.

There is a Fully Expand Tree Node action, which is bound to Numpad * key (*) by default.

But if you use this key, it doesn't expand the whole tree, rather it expands the first level and when you press it again it expands subsequent levels, and so on.

But it can still do what you're trying to achieve. Just click the tree item you want to expand (for example src) in project view, press and hold the * key and all nodes will be expanded pretty quickly. It's not the best way but I'm not aware of any better solution.

Tested on IntelliJ IDEA 14 and 2019.3.3 Ultimate

If you press *: Expand 1 level.

If you press * *: Expand 2 levels.

If you press * * *: Expand 3 levels.

and so on.

You can use right-arrow button to expand the selected node,and keep pressing to expand all node.

Or

Search "Fully Expand Tree Node" in settings->Keymap,find the keyshort,use it,it will expand nodes level by level.The other two command within Others is not useful.

And you can also set mouse shortcut like "ALT+[Wheel Down]",this can help you expand all without one hand leaving the mouse. More efficient,you can Set "Collapse Node" keyshort to "ALT+[Wheel Up]".
