What is Eclipse's Ctrl+O (Show Outline) shortcut equivalent in IntelliJ IDEA?

Question

I like to use Eclipse\'s shortcut Ctrl + O which outlines the current source. Is there an equivalent shortcut in IntelliJ IDEA?

It opens a dial

Answer 1

If you want a persistent/sticky/docked Tool Window instead of a temporary/transient dialog:

• Mac: ⌘+7

Answer 2

Ctrl+F12 works, because it is for file structure popup, which is similar to showing code in Eclipse.

Answer 3

The shortcuts are: Ctrl+Shift+N for files Ctrl+N for classes

Answer 4

Shortcuts:

• Mac: ⌘+F12
• Windows: Ctrl+F12
• Ubuntu/CentOS: Ctrl+F12

Above works on IntelliJ versions 14 to 2020.

Answer 5

For some Linux kinds, and particularly for XFCE (like Xubuntu, Mint XFCE) a lot of default XWin keyboard layout mappings are not working.

This is because they overlap with assigned Window Manager -> Keyboard shortcuts. For the concrete question Ctrl+F12 is assigned to Workspace 12 which I doubt that many use at all.

The solution is to clear those Window manager assignments in Window Manager -> Keyboard tab. As a temporal workaround you may use IDEA actions via Find action Ctrl+Shift+A

There are other overlapping short keys. References:

• Difference between Default and Default XWin keymaps
• Avoid shortcut conflicts in Linux keymap
• File structure on CTRL+F12 dissapeared in 13.1.5

Answer 6

I haven't used Eclipse for years, so I'm not that familiar with the behaviour you're after - but I believe Ctrl + F12 may do what you want: it is the shortcut for the File structure Popup in the default mapping.
