Common shortcuts for eclipse

Searching for eclipse shortcut keys on the Internet, you can find a lot of them. Most of them list more than n shortcut keys. It is estimated that most people will have a big head after reading it. I have a big head, but I tried them one by one and sorted them out. Since eclipse is the most commonly used and most useful, some shortcut keys that must be used to write code are only about half of the online shortcut keys, reducing the amount of memory for everyone. If everyone uses these shortcut keys well, the efficiency of writing code will definitely be improved. Of course, you can also view and modify shortcut key bindings through Window–>Preferences–>General–>Keys in the menu bar.

Alt+ / Content assist (it saves you a lot of keystrokes, it's too common)
Ctrl+D Delete the current line or multiple lines
Alt+↓ The interaction position between the current line and the next line (especially practical, you can save cutting and pasting first)
Alt+↑ the current line and the previous line interactive position (same as above)
Ctrl+Alt+↓ Copy the current line to the next line (copy increase)
Ctrl+Alt+↑ Copy the current line to the previous line (copy increase)
Shift+Enter Insert the next line of the current line Empty line (at this time the mouse can be anywhere in the current line, not necessarily the last)

Select

Search

Ctrl+Shift+K Refer to the selected Word to quickly locate to the previous
Ctrl+J Forward incremental search (press Ctrl+J After that, each letter editor you enter provides quick matching to locate a certain word. If not, it will display not found in the status bar. It is especially useful when looking up a word. To exit this mode, press escape to create )

Ctrl+Shift+U List all lines containing strings

Refactoring

(the shortcut keys for general refactoring are Alt+Shift starts with)
Alt+Shift+R Rename method name, property or variable name (it is my favorite one, especially the Rename of variables and classes, which can save a lot of labor than manual methods)
Alt+ Shift+M Extract the code in a function into a method (this is one of the most common methods in refactoring, especially useful for a lot of mud code)
Alt+Shift+C Modify the function structure (more practical, there are N functions call this method, modify it once)
Alt+Shift+L Extract local variables (you can directly extract some magic numbers and strings into a variable, especially when multiple calls)
Alt+Shift+F Change local variables in Class to field variables (a more practical function)
Alt+Shift+I Merge variables (it may be a bit inappropriate to say Inline)
Alt+Shift+V Move functions and variables (not very commonly used ) )
