IDEA的简单操作方法

# IntelliJ IDEA的安装 #

想必下载按钮大家都知道点哪（.exe是个下拉菜单，自行选择和自己电脑匹配的版本，例：.exe是windos平台），安装包打开基本就是下一步下一步，那我就只补充下版本说明好了。   
①Community：免费的，仅有部分功能，因为能用Maven之类的东西所以还是能干挺多事的   
②Ultimate：收费的，全部功能

IntelliJ IDEA的个性化配置

## 1.颜色主题 ##

IntelliJ IDEA默认是白色系主题，除此之外还提供了一个黑色系主题模板，下为切换方法。   
File→Settings→Editor→Colors&front→Scheme→Darcula

个人认为提供的模板还是挺好看的，如果有特殊需要，可以在Colors&front的左侧子选项栏进行个性化定制

## 2.Javadoc的显示 ##

IntelliJ IDEA里默认鼠标滑过不显示java doc，需要手动开启，否则按Ctrl + Q 查看java docFile→Settings→Editor→General→开启Show quick documentation on mouse move Delay(ms) XXX （Delay值是刷新间隔，单位毫秒，根据你电脑配置&强迫症自行调整）

## IntelliJ IDEA键位 ##

修改按键：   
File→Settings→Keymap下拉菜单 Keymaps 中有Eclipse模板。（不推荐，推荐在默认模板上修改，这样可以保留大部分默认快捷键，便于和同行交流）这个修改界面感觉应该都会用，不多解释了，贴上几个 IDEA 中与Eclipse习惯对应的功能

下为IntelliJ IDEA默认按键模板常见快捷键

## 找回syso…… ##

写Html估计会知道 `div.box>div.item*4`→tab键 意味着什么，IDEA用的也是这种方式。

太多了我不多说了，学会这个就行，自定义Live Templates，自行看图File→Settings→Editor→Live Template
