Used to know this, think its something like Ctrl + ??? + F11. Or something.
I have a class member/property that I would like to change the name of. Unfortunately it is sprinkled all over the class, some 100+ references to it. Throughout the various methods.
Eclipse has a shortcut that allows you to click on an identifier, hit the hotkey (whatever it is), and then modify the text composing the identifier. Then, once you click off of that text, it searches and replaces all references of the "old" identifier and replaces them with the new one.
I know I could just do a search & replace. I don't want that. I want the shortcut/hotkey. And its driving me crazy because I can't find it because I don't know what it's called!
Thanks to any Eclipse gurus that can help.
The shortcut combination is ALT + SHIFT + R.
CTRL+SHIFT+L list of all shortcuts.
The key combination is
Alt + Shift + R
The corresponding menu (and context menu) entry is
Refactor > Rename ...
I wanted to specify that the shortcut is Alt + Command + R if you're using Mac OS X.
PC
The shortcut for rename is:
Alt + Shift + r.
And the list of shortcuts will be displayed with:
Ctrl+Shift+L
Mac OS x
The shortcut defined for rename/refactoring will work:
option + ⌘ + R
The option for rename is:
F2
Both are shortcuts defined for Mac, open the Shortcuts List with
Shift + ⌘ + L:
Simply select the file and press F2. The rename option will open. Other option is ALt + Shift + R. But I prefer F2 is much easier way.
For renaming a file, the F2 works in all cases I've encountered.
However my experience shows that refactoring a class or a method can behave differently in different OS and desktop environments and that they may intercept key modifiers and thus render shortcuts ineffective.
However, eclipse is good at accessing its main menu from the keyboard. For instance, in plasma in linux (tested with eclipse 2019-09 and older) renaming is achieved pressing Alt-T, then releasing it and pressing N afterwards. The Alt-T effectively opens up the refactoring menu and the N orders eclipse to rename the selected element. Actually, the whole refactoring menu can be addressed in that manner, this achieving the goal with less friction.
For Mac, use the below keys
OPTION + COMMAND + R

How can I show(unfold) the hidden(folded) code in IntelliJ IDEA, as shown in the picture below, just using keyboard without touching the mouse?
In IntelliJ IDEA you can use to following shortcuts to fold/unfold code blocks:
To fold and unfold CURRENT selected block of code:
CTRL+- and CTRL++ on Windows;
⌘ CMD+- and ⌘ CMD++ on Mac;
To fold and unfold ALL blocks of code:
CTRL+⇧ SHIFT+- and CTRL+⇧ SHIFT++ on Windows
⌘ CMD+⇧ SHIFT+- and ⌘ CMD+⇧ SHIFT++ on Mac.
By the way, in Settings → Editor → General → Code Folding you can specify the default folding behavior for a various situations (e.g., imports, one-line methods, inner classes, #SuppressWarnings annotations, array literals, generic constructors and many others):
And even after that your folding/unfolding hotkeys listed above will work as well.
To be sure which shortcuts are available go to settings > Keymap
then go to
Main Menu > Code > Folding
Expand
default on mac : cmd+
default on win : ctrl + numpad +
Collapse default on mac : cmd-
default on mac : cmd-
default on win : ctrl + numpad -
The only available option for your need (about import statements) is,
Move your pointer to (+) button on the left hand side of the statement so you can see the pointer changes to hand mark.
Then Ctrl + -
Find this for more info expanding/collapsing code. But this is more about blocks.
Easy to remember steps:
Press SHIFT twice
Type folding
Select Folding action
All options related to Expand and Collapse should be visible now (with keymaps)
Let's say I have the following code:
System.out.println(Math.PI);
Is there a plugin or some setting where I can hover over Math.PI and have IntelliJ tell me the value of the constant?
Press ctrl + q (or ctrl + j on mac) to activate the quick documentation action to see a documentation popup for this constant:
Also you could hover over PI with pressed ctrl:
Furthermore, you always can jump to the source code by ctrl + b.
It's much better to use View Definition feature.
By hitting Ctrl+Shift+I (if you're OSX user Option+Space) you will see the method, function, constant, variable definition in window popup.
Example with Objects#equals method:
Normally you would expect just hovering over a method it would show a popup of the return type.
How do you get this information in intellij ultimate?
Hit Ctrl + Q (or ⌃J on Mac) when cursor is on a method declaration or call. It will show you the pop-up you want. As a bonus: Ctrl + Shift + I will display method body as well in a pop-up.
You hover it and hold down CTRL in windows or CMD in Mac
Try Ctrl + Space for quick definitionAlso Ctrl + Shift + P may help
In intellij, Go to Help > Productivity Guide
you will find a list of useful shortcuts to increase productivity
Regarding, this question in mac Press option+command+V to get the list of names that you can choose
Ctrl+ J in mac for getting the documentation
Find screenshots for ease:-
Ctrl+Shift+P works great with extra bonus by highlighting relevant return expression (IntelliJ 2020.2.3 CE)
Hot key for that: Ctrl + Shift + P
Toolbar: "View->Type Info"
How do I compile my code in Eclipse using keyboard shortcut key? I have Googled this but could not find any answer.
In addition, if you know how to move through different tabs in Eclipse using keyboard short cut key, please tell me that too.
how to move through different tabs in eclipse using keyboard short cut
key
Ctrl + F6, and then tap F6 to navigate through the tabs.
How do I compile my code in eclipse using keyboard shortcut key ?
The shortcut key can be found in the respective menu item. For a list of all Eclipse shortcut keys, use Ctrl + Shift + L
Reference: Effective Eclipse: Shortcut keys.
In Eclipse to find out about the existing keyboard shortcuts or to change them, go to Window menu, click Preferences, in left sidebar expand General and select Keys. The list of commands and their keyboard associations will be on the right. You can use filter to quickly find what you are looking for.
For full project it is ctrl + B (build all), this will compile your code. For individual java class please use ALT + SHIFT + X and then J, this will compile and run the java application.
How to switch between open tabs:
CTRL + F6 will give you a list of open tabs that you can scroll through.
Alt + (left or right arrows) does switch tabs, but it in a very odd way.
Best Approach is : Ctrl + Page Up, Ctrl + Page Down
How to compile:
Ctrl + B is the general way.
A few more useful shortcuts:
http://javarevisited.blogspot.in/2010/10/eclipse-tutorial-most-useful-eclipse.html
ctrl + b will compile your project.
alt + p + n + enter to clean
ctrl + b to build
Use both in this order to rebuild.
On My Linux CTRL + F11 compiles code in Eclipse.
To run code in eclipse use the followed shortcut key
Ctrl + f11
use Ctrl+Shift+L in eclipse to get of shortcut list
If I'm in an interface and pointing to a method name, what can I do to quickly go to the ONLY implementation of that method?
Using Eclipse 3.6.
F3 is the typical "go to implementation". For interfaces that go to the interface definition.
Instead use Ctrl + T to see all implementations of the interface definition. You can then easily go to the one you want with the arrow keys and Enter. I believe that the first one is automatically selected so that Ctrl-T + Enter will do what you need.
I just checked this on my Eclipse 3.6 install: Hold control (command on Mac), hover over the method name and select "Open Implementation".
You may assign a keyboard shortcut to this action by using Window > Preferences > General > Keys and searching for "Open Implementation".
In the keymap (General > Keys) search for "open implementation" and map it to whatever you want. I chose Ctrl + Shift + I. Make sure you select "Editing Java Source" in the When box. I tested it, and having the cursor over the method name and pressing Ctrl + Shift + I took me directly to the implementation instead of showing the hierarchy that you get with Ctrl + T.
Also you can see an answer to a nearly identical question for other options:
In eclipse, ctrl-click goes to the declaration of the method I clicked. For interfaces with one implementation, how can I just directly to that implementation?
If someone still need this information nowadays (Eclipse version 2022), to jump into interface method definition starting from an #Override method, now in Eclipse you can see on the left, next to the method signature, a little white triangle. By clicking on that you will jump to the implemented interface method. here an image of the little triangle
Oterwise, if you are on a interface method definition and you need to jump to one of the implementations, you must use CTRL+T shortcut to see the list of available implementations and than click on one of them.
