Window --> preferences --> general --> keys
Ctrl + 1 quick fix (the most classic shortcut, you don't need to talk about it)
Ctrl + D: delete the current row
Ctrl + Alt + ↓ copy the current row to the next row (copy added)
Ctrl + Alt + & uarr; copy the current row to the previous row (copy added)
Alt + ↓ interaction position between the current row and the following row (especially practical, you can save cutting and pasting)
Alt + & uarr; interaction position between the current row and the preceding row (same as above)
Alt + & larr; previous edited page
Alt + & rarr; the next editing page (for the previous one, of course)
Alt + Enter display the properties of the currently selected resource (Project, or file)
Shift + Enter insert empty rows in the next row of the current row (the mouse can be at any position of the current row, not necessarily the last row)
Shift + Ctrl + Enter insert blank lines in the current line (same principle)
Ctrl + Q locate the last Edited location
Ctrl + L locate in a line (for those with more than 100 programs, there will be good news)
Ctrl + M maximize the current Edit or View (then press it, and vice versa)
Ctrl +/comment out the current row, and then press it to cancel the comment
Ctrl + O quick OutLine display
Ctrl + T quickly display the inheritance structure of the current class
Ctrl + W disable the current Editer
Ctrl + K quickly locate to the next one by referencing the selected Word
Ctrl + E: click it to quickly display the drop-down list of the current Editer (if the current page is not displayed, it is displayed in bold)
Ctrl +/(keypad) collapse all code in the current class
Ctrl + × (keypad) show all the code in the current class
Ctrl + Space code assistant inserts some code (but it is usually in conflict with the input method. You can modify the key of the input method or replace it with Alt +/For the moment)
Ctrl + Shift + E display the managers that manage all opened Views (you can choose to close or activate them)
Ctrl + J forward incremental search (after pressing Ctrl + J, each letter editor you enter provides a quick match to locate a word. If not, it is not found in stutes line. It is particularly useful when querying a word. This function was available two years ago)
Ctrl + Shift + J reverse incremental search (the same as the previous one, but only from the back to the front)
Ctrl + Shift + F4 close all open Editer
Ctrl + Shift + X change all selected text to lowercase
Ctrl + Shift + Y change all selected text to lowercase
Ctrl + Shift + F format the current code
Ctrl + Shift + P locate the matched character (for example, {}) (when positioning from the front, the cursor must be inside the matched character, followed by the front, and vice versa)
The following shortcut keys are commonly used in Refactoring. I like them and want to sort them out frequently (note: The keys for refactoring generally start with Alt + Shift)
Alt + Shift + R Rename (one of my favorite ones, especially the Rename of variables and classes, which saves a lot of Labor compared with manual methods)
Alt + Shift + M extraction 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. N functions call this method and modify it once)
Alt + Shift + L extract local variables (you can directly extract some magic numbers and strings into one variable, especially when multiple calls are performed)
Alt + Shift + F convert the local variable in the Class to the field variable (more practical)
Alt + Shift + I merge variables (this may be a bit inappropriate Inline)
Alt + Shift + V moving functions and variables (not commonly used)
Alt + Shift + Z restructured regret medicine (Undo)
