"If you are doing well, you must first sharpen the tool." Thanks to eclipse, she made it easier for us to read the code of a large project, I found that mastering several eclipse shortcut keys will make the reading experience smoother. Write it out and share it with Zhu Jun. Please add it.
1. CTRL + Left click
This is frequently used by most people to view the definitions of variables, methods, and classes.
2. CTRL + O
View the outline of a class and list its methods and member variables. Tip: press Ctrl + O to list the methods and variables inherited by the class.
Note: "O" ---> "outline" ---> "outline"
3. CTRL + T
View the inheritance tree of a class, which is top-down. If you press Ctrl + T one more time, the structure is displayed from bottom to top.
Tip: select a method name and press Ctrl + T. You can view the parent class, subclass, and interface of the method with the same name.
Note: "T" -------> "Tree" -----> "Hierarchy Tree"
4. Alt + left and right direction keys
We often encounter situations where we read the code by pressing CTRL + left-click, trace them layer by layer, and then get lost in the Code. In this case, we only need to press "Alt + Left-direction key" to return to the last read position, similarly, pressing "Alt + right arrow key" will move to the returned reading position, just like the browser's forward and backward buttons.
5. CTRL + ALT + H
If you want to know whether a class method is called by other classes, select the method name and press CTRL + ALT + H ", eclipse will display the methods called by this method, and ultimately generate a call relationship tree.
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 (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)
CTRL + Shift + u select the selected text, which is very similar to the UE list Query
CTRL + ALT + H view the link level of a function called by other functions
