The way to quickly multi-line comment in eclipse
1. Select the area you want to comment, use ctrl+shift+C to add // comment
2. Select the thing you want to comment first, use shit+ctrl+/ to add /* */ comment
3. To modify For the shortcut keys of commands in eclispe, we just need to enter windows -> preference -> General -> key settings (turn)
Supplement: Select the area to be commented, ctrl+/ will add // comment 2010/09/13
After selecting, ctrl+shift+\, remove the comment of the selected part
(Turn) A list of all shortcut keys in myeclipse is attached: Ctrl+1 quick fix (the most classic shortcut key, needless to say) Ctrl+D: delete the current line Ctrl+Alt+↓ copy the current line to the next line (copy increase ) Ctrl+Alt+↑ Copy the current line to the previous line (copy and increase) Alt+↓ The interaction position between the current line and the next line (especially practical, you can save the first cut and paste) Alt+↑ The current line and the above line interactive position (same as above ) Alt+← Previous edited page Alt+→ Next edited page (of course for the above one) Alt+Enter Display the properties of the currently selected resource (project, or file or file) Shift+Enter in the current line Insert a blank line in the next line (the mouse can be at any position in the current line, not necessarily the last) Shift+Ctrl+Enter Insert a blank line in the current line (the principle is the same as the previous one) Ctrl+Q Position to the last edit place Ctrl+ L locates on a certain line (good news for those with more than 100 programs) Ctrl+M maximizes the current Edit or View (and vice versa) Ctrl+/ Comments the current line, presses again to uncomment Ctrl+O Quickly displays OutLine Ctrl+T Quickly display the inheritance structure of the current class Ctrl+W Close the current Editor Ctrl+K Refer to the selected Word to quickly navigate to the next Ctrl+E Quickly display the drop-down list of the current Editor (if the current page is not displayed in bold) Ctrl+ /(Keypad) Collapse all code in the current class
Ctrl+× (keyboard) Expand all the codes in the current class Ctrl+Space The code assistant completes the insertion of some codes (but generally it conflicts with the input method, you can modify the hotkey of the input method, or you can temporarily use Alt+/ instead) Ctrl +Shift+E Displays the manager that manages all currently opened Views (can choose to close, activate, etc.) Ctrl+J Forward incremental search (after pressing Ctrl+J, each letter editor you enter will be Provides quick matching to locate a word. If not, it will be displayed in the stutes line that it is not found. When looking up a word, it is especially useful. Idea has this function two years ago) Ctrl+Shift+J Reverse incremental search (Same as the previous one, just check from back to front) Ctrl+Shift+F4 Close all open editors Ctrl+Shift+X Change all the currently selected text to lowercase Ctrl+Shift+Y Change all the currently selected text to lowercase Format the current code for lowercase Ctrl+Shift+F Ctrl+Shift+P Locate to the matching character (such as {}) (when positioning from the front to the back, the cursor should be in the matching character, from the back to the front, and vice versa) below Shortcut keys are commonly used in refactoring, I like to sort out the ones I like and commonly use (Note: The shortcut keys for general refactoring all start with Alt+Shift) Alt+Shift+R Rename (my favorite is to use it ) One of them, especially the Rename of variables and classes, 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 muddy code Useful) Alt+Shift+C Modify the function structure (more practical, there are N functions calling this method, modify it once)
Alt+Shift+L Extract local variables (you can directly extract some magic numbers and strings into a variable, especially when calling multiple times) Alt+Shift+F Change the local variable in the Class into a field variable (more practical Function) Alt+Shift+I Merge variables (it may be a bit inappropriate to say this Inline) Alt+Shift+V Move functions and variables (not very commonly used) Alt+Shift+Z Refactoring regret medicine (Undo) Edit scope function shortcut keys Global Find and Replace Ctrl+F Text Editor Find Previous Ctrl+Shift+K Text Editor Find Next Ctrl+K Global Undo Ctrl+Z Global Copy Ctrl+C Global Redo Previous Selection Alt+Shift+↓ Global Cut Ctrl + XGlobal Quick Fix Ctrl1+1Global Content Assist Alt+/ Global Select All Ctrl+ AGlobal DeleteDeleteGlobal Context InformationAlt+?
