Attached a list of all shortcut keys in myeclipse：
Ctrl+1 Quick Repair (I don’t need to say more about the most classic shortcut keys)
Ctrl+D: Delete the current line
Ctrl+Alt+↓ Copy the current line to the next line (copy growth)
Ctrl+Alt+↑ Copy the current line to the previous line (copy growth)
Alt+↓ Interactive status between the current line and the following line (unprecedented and practical, you can save it from cutting first and then pasting)
Alt+↑ Interactive status of the current line and the above line (same as above)
Alt+← Previous edited page
Alt+→ The next edited page (of course, it is for the one above)
Alt+Enter Displays the properties of the currently selected data (project, or file or file)
Shift+Enter inserts blank line on the next line of the current line (this time the mouse can be in any position of the current line, not necessarily the last one)
Shift+Ctrl+Enter Insert blank lines in the current line (the principle is the same as the previous article)
Ctrl+Q Position to the last edited place
Ctrl+L is positioned in a certain line (there is a blessing for those with laws that exceed 100)
Ctrl+M Maximizes the current Edit or View (press the other way around)
Ctrl+/ Comment the current line, and then press it to invalidate the comment
Ctrl+O Quick Display OutLine
Ctrl+T quickly displays the continuous layout of the current class
Ctrl+W Enclose the current Editor
Ctrl+K Refer to the selected Word to quickly locate the next one
Ctrl+E Quickly display the drop-down list of the current Editer (if the current page is not displayed in bold)
Ctrl+/ (keyboard) collapses all codes in the current class
Ctrl+× (keyboard) Expand all codes in the current class
Ctrl+Space code assistant completes the insertion of some codes (but generally conflicts with the input method. You can correct the hotkeys of the input method, or you can temporarily use Alt+/ to replace it)
Ctrl+Shift+E Displays the communication and management device of all views currently opened by the communication and management (can choose to close, activate, etc. to operate)
Ctrl+J Forward incremental search (after pressing Ctrl+J, each letter editor you enter provides quick matches to locate a certain word. If not, it will not be found in the stutes line. It is rare and practical when searching for a word. This function Idea was available two years ago)
Ctrl+Shift+J Reverse incremental search (similar to the previous one, but it is a search from behind to front)
Ctrl+Shift+F4 Enclose all open Editors
Ctrl+Shift+X Deodorize all currently selected text in lowercase
Ctrl+Shift+Y Change all currently selected text to lowercase
Ctrl+Shift+F Layout the current code
Ctrl+Shift+P Position the matching character (for example, {}) (When the domain is positioned behind, the cursor must be in the matching character, and the back to the front, otherwise)
The following shortcut keys are commonly used in reconstruction. I like and use them to clean up (Note: Generally, the shortcut keys for reconstruction are started by Alt+Shift)
Alt+Shift+R rename (I am my favorite one, especially the Rename of variables and classes, which can save a lot of labor than manual methods)
Alt+Shift+M extraction method (This is one of the most commonly used methods in refactoring, especially for a lot of mud balls of code)
Alt+Shift+C Revise the function layout (Doujin is practical, there are N functions that call this method, and it can be corrected in one go)
Alt+Shift+L extracts local variables (you can directly extract some magic numbers and strings into one variable, especially when multiple calls are called)
Alt+Shift+F Change the local variable in Class into a field variable (a practical function of Doujin)
Alt+Shift+I merge variables (maybe it is a bit inappropriate inline)
Alt+Shift+V Move functions and variables (not very commonly used)
Alt+Shift+Z Reconstructed Repentance Medicine (Undo)
