提问by DIA Tom
Alright it can be a lame question, but everybody uses these things differently. What's some of the best time savers out there for this IDE.
Tom
好吧，这可能是一个蹩脚的问题，但每个人都以不同的方式使用这些东西。此 IDE 有哪些最佳节省时间的方法。

Ctrl+f then tick the "Regular expressions" checkbox. From that, you can search with regular expressions, but even more powerfully, you can include group matches in your replacement string ($1, $2, etc, or $0 for the whole match).
Ctrl+f 然后勾选“正则表达式”复选框。由此，您可以使用正则表达式进行搜索，但更强大的是，您可以在替换字符串中包含组匹配（$1、$2 等，或整个匹配的 $0）。

Ctrl+Shift+Oto organize imports, which will format them nicely, remove unneeded imports, and add missing imports.
Ctrl+ Shift+O来组织导入，这将很好地格式化它们，删除不需要的导入，并添加丢失的导入。

ctrl-shift-r and its buddy, ctrl-shift-t, to open a resource or type, respectively. Resources includes all files in your open projects (including non-java files), and types includes java types either in your projects, or in a library included in the projects.
ctrl-shift-r 及其伙伴 ctrl-shift-t 分别打开资源或类型。资源包括您打开的项目中的所有文件（包括非 java 文件），类型包括您的项目中或项目中包含的库中的 java 类型。

- CTRL-SHIFT-g : finds usages of the method or field under the cursor, absolutely necessary for understanding code
- CTRL-F6 : navigate between the list of open editor windows, if you just type it once and let go you toggle back to the previous editor window, doing this successively is a nice way to jump back and forth
- CTRL-t : on a class or method will show you the type hierarchy, very useful for finding implementations of an interface method for example
- CTRL-SHIFT-g ：查找光标下的方法或字段的用法，对于理解代码绝对必要
- CTRL-F6 : 在打开的编辑器窗口列表之间导航，如果你只输入一次然后放开你切换回上一个编辑器窗口，连续这样做是来回跳转的好方法
- CTRL-t ：在类或方法上将显示类型层次结构，例如对于查找接口方法的实现非常有用

Save Actions rocks. There you can get your Imports organized (Ctrl+Shift+o) and formatting of code (CTRL + SHIFT + f). Besides from that i love ALt + Shift + R for refactoring.
保存操作岩石。在那里你可以组织你的导入 (Ctrl+Shift+o) 和代码格式 (CTRL + SHIFT + f)。除此之外，我喜欢 ALt + Shift + R 进行重构。
My favorite things is the plugins though: They might cause you to use more time but most of the time they give quality (subjective I know)
不过，我最喜欢的东西是插件：它们可能会导致您使用更多时间，但大多数时候它们会提供质量（我知道是主观的）
- Code coveragde (ECLEMMA)
- Static analysis on source(PMD)
- Static analysis on byte code(FindBugs)
- CheckStyle
- SpringIDE.
- 代码覆盖率 (ECLEMMA)
- 源静态分析（PMD）
- 字节码静态分析(FindBugs)
- 检查样式
- 弹簧IDE。
Then you start to rock with the mandatory source control plugins and the maven 2 plugin.
然后你开始使用强制性的源代码控制插件和 maven 2 插件。
Rock on!
摇滚吧！

Alt-Up Arrow moves the current selection up a line, Alt-Down Arrow moves it down. I also use Alt-Shift-Up/Down Arrow all the time. Ctrl-K and Ctrl-Shift-K is quite handy, finding next/previous occurrence of the current selection (or the last Find, if nothing is selected).
Alt-Up Arrow 将当前选择向上移动一行，Alt-Down Arrow 将其向下移动。我也一直使用 Alt-Shift-Up/Down Arrow。Ctrl-K 和 Ctrl-Shift-K 非常方便，查找当前选择的下一个/上一个出现（或最后一个 Find，如果没有选择）。
