IntelliJ IDEA 14.1.0 Help

Quick Pop-up Windows

Quick pop-ups are helpful for checking additional information related to the symbol at the caret. Here is a list of popups you should know, if you want to be more productive.

Parameter info

The information on parameters required for a particular method is available via Ctrl+P shortcut. The pop-up shows the matched overloaded method, highlighting the current parameter.

Refer to the section Viewing Method Parameter Information.

Viewing information

This section gives but a brief overview. For details, refer to the section Viewing reference information in the suggestion lists.


The documentation pop-up is one of the most used editor features. To see the documentation, just press Ctrl+Q.

Quick definition

If you want to quickly look at the implementation of a symbol at the caret, you can call the Quick Definition by pressing Ctrl+Shift+I.

Pin pop-ups

If you want to keep the documentation open, click the Pin button pin in the top right corner. The pop-up will show documentation for the current symbol.

Dock pop-up

If you don’t like floating pop-up windows, you can dock them as a tool window by using the gear button cogwheel_framed in the top right-hand corner.

Refer to the section Ways to control the viewing modes for the tool windows.

Pop-ups in other components

It is well-known that Quick pop-ups are available for symbols in the editor. However, they are also available for items in any other list, via the same shortcuts Ctrl+Q and Ctrl+Shift+I.

Read about viewing reference information in the suggestion lists here.

You can use quick pop-ups even if you browse the elements from the Navigation bar via Alt+Home.

Show usages

Show usages is a very simple but powerful feature. Just press Ctrl+Alt+F7 and get a list of usages for any symbol at the caret.

Refer to the section Viewing Usages of a Symbol for details.
