How to show(unfold) the hidden(folded) code in Intellij-IDEA with keyboard shortcut?

Question

How can I show(unfold) the hidden(folded) code in IntelliJ IDEA, as shown in the picture below, just using keyboard without touching the mouse?

Answer 1

In IntelliJ IDEA you can use to following shortcuts to fold/unfold code blocks:

• To fold and unfold CURRENT selected block of code:
  • CTRL + - and CTRL + + on Windows;
  • ⌘ CMD + - and ⌘ CMD + + on Mac;
• To fold and unfold ALL blocks of code:
  • CTRL + ⇧ SHIFT + - and CTRL + ⇧ SHIFT + + on Windows
  • ⌘ CMD + ⇧ SHIFT + - and ⌘ CMD + ⇧ SHIFT + + on Mac.

---

By the way, in Settings → Editor → General → Code Folding you can specify the default folding behavior for a various situations (eg, imports , one-line methods , inner classes , @SuppressWarnings annotations , array literals , generic constructors and many others):

And even after that your folding/unfolding hotkeys listed above will work as well.

Answer 2

To be sure which shortcuts are available go to settings > Keymap

then go to

Main Menu > Code > Folding

Expand default on mac : cmd+ default on win : ctrl + numpad + Collapse default on mac : cmd- default on mac : cmd- default on win : ctrl + numpad -

Answer 3

The only available option for your need (about import statements) is,

• Move your pointer to (+) button on the left hand side of the statement so you can see the pointer changes to hand mark.

• Then Ctrl + -

Find this for more info expanding/collapsing code. But this is more about blocks.

Answer 4

Easy to remember steps:

• Press SHIFT twice
• Type folding
• Select Folding action
• All options related to Expand and Collapse should be visible now (with keymaps)
