Eclipse Common shortcut keys

Type	Shortcut keys	Describe
Edit	Ctrl+1	Quick fix (the most classic shortcuts, you don't have to say, you can solve a lot of problems, such as import class, try catch surrounded, etc.)
	Ctrl+shift+f	Formatting the current Code
	Ctrl+shift+m	To add import imports for a class
	Ctrl+shift+o	Import imports of organizational classes (both Ctrl+shift+m and can help you remove useless imports, useful)
	Ctrl+y	Redo (contrary to undo Ctrl + Z)
	alt+/	Content assist (how many times you save the keyboard beat, too often)
	Ctrl+d	Delete the current line or multiple rows
	Alt+↓	The current line and the following line of interaction (particularly practical, can be omitted first cut, then pasted)
	Alt+↑	The current line and the previous row interaction position (IBID.)
	Ctrl+alt+↓	Copy the current row to the next row (copy incremented)
	Ctrl+alt+↑	Copy the current line to the previous row (copy incremented)
	Shift+enter	Inserts a blank row on the next line of the current row (at which point the mouse can be at any position in the current row, not necessarily the last)
	ctrl+/	Comment on the current line, and then cancel the comment
Choose	Alt+shift+↑	Select Encapsulated Element
	alt+shift+←	Select Previous Element
	alt+shift+→	Select the next element
	shift+←	Select a character from the cursor at the left
	shift+→	Select a character from the cursor at the right
	ctrl+shift+←	Select the word to the left of the cursor
	ctrl+shift+→	Select the word with the cursor and edge
Move	ctrl+←	The cursor moves to the beginning of the word on the left, the equivalent of Vim's B
	ctrl+→	The cursor moves to the end of the right word, the equivalent of Vim's E
Search	Ctrl+k	Click the selected word to quickly navigate to the next (if Word is not selected, search for Word last used search)
	Ctrl+shift+k	Refer to the selected word to quickly navigate to the previous
	Ctrl+j	Forward incremental lookup (after pressing CTRL+J, each letter editor you enter provides a quick match to navigate to a word, if not, the status bar shows no found, check a word, especially useful, to exit this mode, according to escape to build)
	Ctrl+shift+j	Reverse incremental lookup (same as above, except forward)
	Ctrl+shift+u	List all rows that contain strings
	Ctrl+h	Open the Search dialog box

	Ctrl+shift+d	Display the value of a variable
	Ctrl+shift+b	Set or remove breakpoints on the current line
	Ctrl+r	Run To line (super easy to use, can save a lot of breakpoints)
Refactoring	Alt+shift+r	Rename a method name, attribute, or variable name (it's my favorite, especially the rename of variables and classes, which can save a lot of labor than a manual approach)
	Alt+shift+m	Extracting code from a function into a method (which is one of the most common methods of refactoring, especially useful for a lot of mud code)
	Alt+shift+c	Modify the function structure (more practical, there are n functions called this method, modified once done)
	Alt+shift+l	Extract local variables (you can directly extract some magic numbers and strings into a variable, especially when multiple calls are made)
	Alt+shift+f	Change the local variable in class to a field variable (more useful function)
	Alt+shift+i	Merge variables (this might be a bit inappropriate inline)
	Alt+shift+v	Move functions and variables (not commonly used)
