Eclipse shortcut 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 + ↓ 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 + ↑ interaction between the current row and the previous row (same as above)
Alt + ↓ previous edited page
Alt + → next edited page (of course for the above)

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 (ProgramMore than 100 of people have the Gospel)
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)
