Drop the mouse and use the best Eclipse shortcut keys _eclipse

There are many articles about eclipse shortcuts, but most of them are not detailed and are not illustrated. This article will introduce a truly useful eclipse shortcut that can be developed programmatically without a mouse.

I'm also going to put some of the knowledge points related to eclipse, as a series, you can write "How to debug, set exception breakpoints, evaluate expressions in debug mode", "Refactor", "Practical Eclipse manipulation techniques," and so on, in addition to shortcuts, so you just learn Java friends, You can use eclipse in a more comprehensive way.

The more shortcuts you use, the more efficient your operations are, and the more efficient your development will be, and it will allow you to focus more on the code rather than always letting your mouse divide your God.

This article just lists some of the most common eclipse shortcuts, and you'll add some handy shortcuts in succession. The first recruit: three ways to switch files 1, Ctrl + E, display all the files currently open on the right.

2, Ctrl + PG UP, Ctrl + PG Dn, file hopping.

Press CTRL + Pg Dn, jump from Adconf.java to Adquaryserviceimpl.java

Before:

After:

Vice versa. 3, Ctrl + F6, in the current file to display all currently open files

I personally like Ctrl + E this way. Second trick: Copy the current line or the currently selected code block

In eclipse, if you need to copy a row without using CTRL + C, you just need to use CTRL + Alt +↓. Note that this shortcut is usually a conflict and can be modified on the Keys panel. I like to replace CTRL + ALT +↓ with CTRL + ALT + END.

public class TestString {

public static void Main (string[] args) {

String s = "";

System.out.println (s = = null);

}

}

Suppose you want to copy the line "String s =" ", just focus on the row it corresponds to, and then press CTRL + ALT +↓." This shortcut also supports copying blocks of code. The third trick: Show all the properties and methods of the current class

It used to be in Eclipse's outline, and now you can turn it off because you can use CTRL + O to display all the properties and methods of the current file. Note that the capital letter O, not the number 0.
Part Four: Ctrl + W Close the current file, CTRL + Shift + W Close all files Five strokes: Quickly locate the location of the current file in the project, that is, the position in the package view

One way is to click "Link with Editor" in the package view directly.

But this way has a disadvantage, that is, you must use the mouse to click "Link with Editor".

The second way is to use ALT + Shift +w to display the view and then select Package view, and also navigate to the position of the current file in the package view, thus avoiding the use of the mouse.

Recruit: Select the contents of the Java file

public string Get (@RequestParam (value = "key") string key) {

Object obj = oscacheservice.get (key);

return Jsonutil.tojson (obj);

}

Return "";

}

If you position the mouse over the Oscacheservice, you can use ALT + Shift +→ to select Oscacheservice the entire string without using the mouse.

This shortcut is very useful, and if you want to select all the content in the IF statement, you can also use this shortcut, and so on. Seventh recruit: Ctrl + T select Java File, CTRL + R Select Resource File

If you're just looking for Java classes, it's more efficient to use CTRL + T directly.

Eighth recruit: Ctrl + H for global search and local search in addition to "File search", other can be removed from the view
