Ctrl+1 Quick Fix (the most classic shortcuts, you don't have to say more)
Ctrl+d: Delete When moving forward
Ctrl+alt+↓ Copy the current row to the next row (replication incremented)
Ctrl+alt+↑ Copy the current line to the previous row (replication incremented)
Alt+↓ the current line and the next line of interaction (especially useful, can be omitted first cut, then pasted)
Alt+↑ the current line and the upper row interaction position (IBID.)
alt+← the previous edited page
alt+→ next Edit page (of course, for the above article)
Alt+enter displays the properties of the currently selected resource (project, or file or file)
Shift+enter inserts a blank row on the next line of the current row (at which point the mouse can be at any position in the current row, not necessarily the last)
Shift+ctrl+enter Insert blank line in current line (principle above)
Ctrl+q positioning to the last edited place
Ctrl+l positioning in a row (for people with programs over 100 have the gospel)
Ctrl+m maximize the current edit or view (and vice versa)
ctrl+/comment on the current line, and then uncomment it
Ctrl+o Quick Display OutLine
Ctrl+t quickly displays the inheritance structure of the current class
Ctrl+w Closing the current editer
Ctrl+k the selected word quickly navigates to the next
Ctrl+e quick display of the current Editer drop-down list (in bold if the current page does not appear)
ctrl+/(numpad) collapses all code in the current class
Ctrl+x (keypad) expands all code in the current class
Ctrl+space Code Helper to complete the insertion of some code (but the general and IME conflict, you can modify the input method hotkey, you can also take up alt+/to replace)
Ctrl+shift+e Display manager that manages all of the currently open view (you can choose to close, activate, and so on)
Ctrl+j forward Incremental lookup (after pressing CTRL+J, each letter editor you enter provides a quick match to navigate to a word, if not, it is not found in the Stutes line, check a word, especially useful, this function idea two years ago)
CTRL+SHIFT+J Reverse incremental lookup (same as above, except forward)
Ctrl+shift+f4 Close all open editer
Ctrl+shift+x the text that is currently selected is all stale lowercase
Ctrl+shift+y turns the currently selected text to lowercase
Ctrl+shift+f formatting of the current code
Ctrl+shift+p position to the match (for example {}) (after locating from the front, the cursor is in the match, back to front, or vice versa)
The following shortcut keys are commonly used in refactoring, I like and commonly used to organize (Note: The shortcut keys for general refactoring are all beginning with alt+shift)
Alt+shift+r rename (is my own favorite, especially the variables and classes of rename, than the manual method can save a lot of labor)
Alt+shift+m Extraction Method (This is one of the most common methods of refactoring, especially useful for a whole bunch of mud codes)
Alt+shift+c Modify the function structure (more practical, there are n functions called this method, modified once done)
Alt+shift+l extract Local variables (you can directly extract some magical numbers and strings into a variable, especially when multiple calls are made)
Alt+shift+f change the local variable in class to a field variable (more useful function)
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 reconstruction of Regret medicine (Undo)
