Shortcuts related to editing

Eclipse has the following editing shortcuts.

1.【ALT+/】

This shortcut key is a good helper for users to edit. It can provide users with content assistance. Don't worry about remembering all the names of methods and attributes. When you can't remember all the names of classes, methods and attributes, experience the benefits brought by ALT+/shortcut key.

2.【Ctrl+O】

Displays an outline of methods and attributes in a class, quickly locates methods and attributes of a class, and is useful when looking for bugs.

3.【Ctrl+/】

Quick comment, can quickly add comments or uncomment for the cursor line or selected line, in debugging may always need to comment something or uncomment, now OK, do not need to repeat comments on each line.

4.【Ctrl+D】

Delete the current line, which is one of my favorites. You don't have to press delete so many times to delete a line.

5.【Ctrl+M】

Maximize and restore windows. When users operate in windows, they always feel that the current window is small (especially when writing code). Now, try the Ctrl+M shortcut key.

View and locate shortcuts

In the program, quickly locate the location of the code, quickly find the location of the Bug, is very difficult, Eclipse provides a powerful search function, you can use the following shortcut keys to help complete the work of locating.

Quickly look up and down the selection, eliminating the need to click the Find dialog box with the mouse.

3.【Ctrl+Shift+R】

Corresponding to Ctrl+Shift+T, find all files (including Java files) in Workspace, or use wildcards.

4.【Ctrl+Shift+G】

Find references to classes, methods, and attributes. This is a very useful shortcut key, for example, to modify the code that references a method, you can use the Ctrl+Shift+G shortcut key to quickly locate all the locations that reference this method.

Quickly generate import, when copying a program from the Internet, do not know how to import into the called class, try the Ctrl+Shift+O shortcut key, there will be surprises.

7.【ALT+Shift+W】

Find the path in the project where the current file is located. This shortcut key can be used to quickly locate the browser view. This shortcut key is useful if you want to find the package where a file is located (especially in larger projects).

8.【Ctrl+L】

Navigate to a line in the current editor, which also works for non-Java files.

9.【Alt+←】、【Alt+→】

Backward history and forward history are very useful when tracking code. Users may find several related places, but they may not remember clearly. You can locate the order of search through these two shortcut keys.
