IntelliJ idea Common Shortcuts Mac version

ALT + ENTER Quick Import class

ALT + Command format code

SHIFT + CONTROL + F Search All Files

SHIFT + COMMAND + u case Conversion

Command + ALT + T
Using * to surround the selected lines of code (* including if, while, try catch, and so on) is also handy, putting what I had to do before: ① first write If-else,② and then adjust the indentation format of the code, and pay attention to whether the parentheses match, now use this function to do, It's much easier (but it makes me lazier)

F2/shift + F2
Jump to the next/previous Error statement the idea provides a convenient jump between error statements, you can use this shortcut to quickly jump between the wrong statement.

Command + Alt + O
Optimizing import automatically removes useless import statements, a pretty good feature.

Command +//[
Jump to the end of the code block/start, this feature VI also have, but also a very common code editing function.

Preferences=>appearance=>theme=>darcula

Preferences=>keymaps

Auto-complement:

The default is Clt+space under Mac, and you can use Keymaps=>main menu=>code=>competion settings. A better place than Eclipse is spring, maven XML, and even the Freemarker template and Ibatis sqlmap support highlighting and automatic completion.

To remove the case sensitivity of auto-completion:

Do not know how many children's shoes and I have been spoiled by eclipse, the use of automatic completion is completely not attention to the case, IntelliJ default case-sensitive, very sad. However, in Editor=>code completion, the case sensitive completion set to none is OK.

Expand catalogs Automatically

Eclipse has the ability to automatically expand the directory by opening a file, and in IntelliJ select AutoScroll to Source and AutoScroll from source on the gears in the left column of project.

Automatic compilation

IntelliJ idea the default JDK version changes

IntelliJ The default is not to automatically compile the project, so before run there will be a make process, the habit of automatically compiling the project can be opened here: Compiler=>make Project automatically. Because the IntelliJ project has little space, it will not have a build workspace like Eclipse for a long time after it is turned on.

IntelliJ idea by default, the version of the JDK used is 1.6, and when you first start idea, if the system does not have a JDK installed, the system automatically downloads the JDK installation files to the Apple website. If your system has a jdk1.7 or higher version, it will also require you to install Apple's website jdk1.6 the first time you open idea. To avoid redundant JDK installations, the solution is as follows: Find IntelliJ idea 13 under/applications, right-click-> Display package content->contents-> Info.plist, use a text editor or the default Xcode to open the file and find

Find IntelliJ Idea 13 under/applications, right-click-> Display package content->contents->info.plist, open the file using a text editor or the default Xcode, and locate the following code

Change <string>1.6*</string> to <string>1.7*</string> save.

The JDK used by idea at this point is version 1.7 and above.
