In IntelliJ IDEA 9 (Maia), we’ve slightly changed the way you run and debug your applications. You’re still able to quickly run or debug a previous configuration (Shift+F10/F9), as well as to create and run/debug a temporary configuration in a context-dependent manner (Ctrl+Shift+F10/F9). However, it’s now much easier to select and run/debug different configurations from the keyboard.

In IntelliJ IDEA 9, you can choose a configuration that you wish to run with one of the following shortcuts:

• Alt+Shift+F9 to debug your application.
• Alt+Shift+F10 to run it.

Invoking any of these actions displays a pop-up window with available configurations, like this:

You can edit a configuration before launch (press F4) or show a configuration dialog box to edit all your configurations and their default settings (press 0). You can also instantly delete a temporary configuration by pressing Delete.

That’s not the end of the story: you’re now able to temporary switch to an opposite action directly from this pop-up window by pressing and holding Shift. When you do that, Run becomes Debug and vice versa.

And even more: we’ve extended the pop-up window with context-dependent configurations. That means whenever you press Alt+Shift+F10 right in a test method’s body, the pop-up displays a temporary configuration to run the current method only or all tests from the current test class.

We’ve also added a number of quick access shortcuts:

• 1 for a previously selected configuration.
• 2 and 3 for context-dependent configurations.
• 0 to display the Edit Configuration dialog box.

One more tip: we’ve mapped this pop-up to F9 (debugger’s Resume Program action). The pop-up now displays on pressing F9 when you’re unable to actually resume anything - that is, when you’re not yet running any debug session.

There’s a lot of useful actions in IntelliJ IDEA that don’t have shortcuts for many different reasons: they’re not used too often or there’s simply no more convenient key combinations left.

For example, I often want to get access to VCS actions like Compare with latest repository version or Revert current file or even submit a single file with a quick NPE fix without opening a menu or going to Changes view.

So how can I call any of these actions with a single shortcut? That’s really easy: I just need to define my own Quick List and map it to a shortcut (Control-X in my case). After I’ve done that, every time I press Control-X I will get a pop-up like this:

Quick List in action

Now I can press 5 to quickly commit the current file or 2 to revert all my changes. OK, now let’s see how to create a Quick List and assign it a shortcut.

IntelliJ IDEA 9 (Maia) lets you assign custom colors to arbitrary sets of files (Scopes) in Editor tabs or Navigation lists (Go to class/file, etc):


This helps you even more quickly than before understand which class you are looking at: JDK, a library, or your own app. The feature is available in Maia builds that you can get from EAP under Settings/File Colors.
