Java and Android: shortcut keys in eclipse (Classic favorites)

1. Select the area you want to add comments to, and press ctrl + shift + C to add // comments.
2. Select the device you want to comment on, and use shit + ctrl +/to add/**/comment.
3. To correct the shortcut key style of the number order in eclispe, you only need to go to windows> preference> General> key settings)
Add: select the area to be annotated, ctrl +/Add // comment 2010/09/13
After the project is selected, press ctrl + shift + \ to remove the comments of the selected project group.

Appendix: List of all shortcut keys in myeclipse:
Ctrl + 1 quick fix (the most classic shortcut key is enough)
Ctrl + D: Delete the current row
Ctrl + Alt + ↓ copy the current row to the next row (copy grows)
Ctrl + Alt + ↓ copy the current row to the previous row (copy grows)
Alt + ↑ the interaction status between the current row and the following row (Xihan is practical, you can save cutting and pasting)
Alt + ↑ interaction between the current row and the top row (same as above)
Alt + ↓ previous edited page
Alt + → next Edit page (for the top one, of course)
Alt + Enter display the properties of the currently selected data (project, or file)
Shift + Enter insert blank lines in the next row of the current row (the mouse can be in any position of the current row, not necessarily the end)
Shift + Ctrl + Enter insert blank lines in the current row (same as above)
Ctrl + Q locate the Last edited location
Ctrl + L positioning in a certain line (for those with a law that spans 100, there will be good news)
Ctrl + M maximize the current Edit or View (then press it, and vice versa)
Ctrl +/comment on the current row, and then press it to invalidate the comment
Ctrl + O quick OutLine display
Ctrl + T to quickly display the continuous layout of the current class
Ctrl + W close the current Editer
Ctrl + K quickly locate to the next one by referencing the selected Word
Ctrl + E: Quickly display the drop-down list of the current Editer (if the current page is not displayed, use a simhei prompt)
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 usually conflicts with the input method. You can correct the Input key, or use Alt +/for replacement)
Ctrl + Shift + E display the administrator of all views currently opened (you can choose to disable, activate, and perform other operations)
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 practical to query a word. This feature was available two years ago)
Ctrl + Shift + J reverse incremental search (similar to the previous one, but 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 current Code
Ctrl + Shift + P locate the matched character (for example, {}) (when the domain is located before it, the cursor must be inside the match character, followed by the front, and vice versa)

The following shortcut keys are commonly used in refactoring. I prefer and usually clean them up (Note: Generally, the refactoring shortcut keys are Alt + Shift)
Alt + Shift + R Rename (one of my favorite ones, especially the Rename of variables and classes, which is much more labor-saving than manual methods)
Alt + Shift + M extraction method (this is one of the most common methods in refactoring, especially for a lot of mud code)
Alt + Shift + C correct the function layout (strong and practical, N functions have called this method, correct 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 made)
Alt + Shift + F convert the local variable in the Class into the field variable (a practical function)
Alt + Shift + I merge variables (it may be a bit inappropriate Inline)
Alt + Shift + V moving functions and variables (not commonly used)
Alt + Shift + Z restructured regret medicine (Undo)
