How do I customize the behavior of "cut" in Eclipse? - eclipse

My normal IDE is Visual Studio, but I'm currently doing some development in Eclipse for the first time. If you press Ctrl-X with text selected in either program, it cuts the text and puts on the clipboard exactly as you'd expect. If press Ctrl-X with no text selected in Visual Studio, it cuts the current line. In Eclipse it is ignored. Is there a way to get Eclipse to use Studio's behavior?

I haven't found a way to make Ctrl+X context sensitive, but I did find that you can bind a key to the "Cut Line" command by going to the Window -> Preferences -> General -> Keys dialog. Unfortunately this always cuts the entire line, even when you have only part of it selected. Maybe binding another key to this command will work for you?

What is the equivalent shortcut for CTRL+D ("add selection to next find match") of VSCode in CLion?

Usually in Visual Studio Code, if I want to delete or modify a certain word from my file, I can highlight one of the words and then continuously press CTRL+D to highlight the rest of that same word in the file. But, in CLion, I am unable to find the equivalent shortcut.
I've Googled and searched here on StackOverflow but no luck. Maybe this shortcut doesn't exist in CLion? Can anyone confirm?
EDIT: It's also known as "Select next occurence" in other JetBrains products.
EDIT: The answer is ALT+J
it is alt+j in all of jetbrains products
So I just want to hit on a couple of options that you have, because I work with both CLion & VSCode as well, and needed the same exact keybinding in CLion.
KEYBINDING FUNCTIONALITY SEMANTICS
Unfortunately, it appears that no one cares about standardizing semantics when it comes to editor functionality/features, and keybindings. It can make moving from one editor to the next difficult, and flat out something many people just would rather not have to do.
Please Note:
_I am no expert on JetBrains IDE's, I am somewhat of an expert with VSCode though. I say this because, IDK how much JetBrains IDE's vary from one to the next, however, from having CLion, IntelliJ, and Access to Ryder I can tell you that in the standard IDE's the keymappings seem near Identical, but in Ryder, the keybindings are totally different.
DEV ENVIRONMENT
BOUND-KEYS (dev env's default)
SEMANTICS
CLion
ALT+J
"Add Selection for Next Occurrence"
Visual Studio Code
CTRL+D
"editor.action.addSelectionToNextFindMatch"
Visual Studio 2022 (IDE)
SHIFT+ALT+.
"Edit.insertNextMatchingCaret"
the The correct semantics for referring to the functionality you seek in CLion is contingent on the environment that its being implemented in. The following demonstrates how to correctly reference it in both JetBrains & Visual Studio Environments:
Add Selection To Next Find Match Ctrl+D editor.action.addSelectionToNextFindMatch
Once you know the semantics of the functionality that you want to customize, you no longer have to resort to using any editors default key mapping. You asked about, CLion, so I will demonstrate, in an image (or screenshot) below, how you can change the keybinding to be anything you want it to be.
To get to the window you see in the photo navigate by following the steps below.
Starting from the text editor, find the word 'FILE' on the 'MENUBAR' located at the very top of your screen.
Click on 'FILE' to drop open the 'FILE MENU'.
Scan through the __FILE MENU'_s ITEMS, until you see the selectable ITEM named 'SETTINGS' (it will have a wrench icon next to it).
4 Select 'SETTINGS' by left-clicking it, and you'll open the 'SETTINGS MENU' open.
Another 'LIST' will appear on the left side. There will be 'BOLD ITEMS' and regular weighted SUB ITEMS. Find the 'BOLD ITEM' that reads 'KEYMAP'.
Select 'KEYMAP'.
The image above shows the view in my IDE of the keymap menu. You can see a red arrow, as well as a green arrow, in the image.
GREEN ARROW
The green arrow shows where you can change the entire Keymap, as you can see in the image, mine is set to VSCode, and as far as I can tell, every keybinding is the same as in VSCode. You do have to download the VSCode keymap plugin though.
RED ARROW
The red arrow shows where the "Bound Keys" are listed. Right click on the keybinding and you'll see a menu that reads
Add Mouse Shortcut
Add Keyboard Shortcut
Add Abbreviation
"it may also have options for removing keybindings and mouse shortcuts, it all depends on how the keybinding you click on is configured"
To set the keybinding select Add Keyboard shortcut, and set it to what ever you want.

Android studio, Ctrl+BackSpace delete same as eclipse

I migrated from Eclipse to Android Studio, but I loved eclipse ability to delete camelCase names by Ctrl+backspace. It deletes from current position of cursor to the first Capital word in Eclipse, but Android Studio deletes the whole word with the same shortcut. How can I do he same as eclipse in AS?
The second question is about scrolling- in Eclipse Ctrl+Mouse Wheel cases scrolling a page, is it possible to do the same in AS?
Open up your Android Studio keymap by going to File > Settings, then selecting "Keymap" on the left.
The first option (Eclipse's Ctrl + Backspace) is called "Delete to Word Start in Different 'CamelHumps' Mode." You can assign it to whatever keybinding works best for you.
As for the second option- it sounds like PageUp and PageDown provide the functionality you are looking for. I'm not aware of a way to make the mouse's scroll wheel perform page scrolling.
To delete one word at a time using CTRL+backspace turn this setting on:
File -> Settings -> Editor -> Smart Keys -> "Use CamelHumps words"

How Do I Switch Between Multiple Eclipse Windows (in "Split Screen" Mode)

Eclipse allows you to open more than one text editing "window" at a time to get a "split screen" effect. This is great, but the problem I'm having is that there doesn't seem to be any way to switch between these windows, directly.
Now, you can use the usual commands (Ctrl+Page Down, CTRL+e, ALT+RIGHT, etc.) to switch between specific buffers. In other words, if I have window 1 with A.java and B.java open, and window 2 with C.java open, I can use Ctrl+Page Down to go from A, to B, to C. However, I can't just go from A or B (ie. from window 1) in to C (ie. to window 2), unless I use CTRL+e and type in "C.java".
There are half a million Eclipse commands though, and they're certainly not all labeled consistently, so it's quite possible I'm just failing to find the relevant command. Does anyone out there in SO-land happen to know it?
By default, its Ctrl+F6. However, its useful if you map you keys to Ctrl+Tab to switch between open editors like Windows.
You can change your preferred keys in Window>Preferences>General>Keys and change "Next Editor" to any key of your choice(Ex: Ctrl+Tab). Hope this is what you needed.
This can be achieved easily if you are using Vrapper in Eclipse. Vrapper
is a Vim plugin for Eclipse. If you are trying to maximize your productivity in Eclipse like we all are, it's well worth the try.
Once you got it installed, check out the Split Editor Plugin for Vrapper. You can then create splits on the fly and switch between them using the standard Vim shortcut: Ctrl-w w
Bonus: don't forget to maxmize your editors using Ctrl-m. If your editor ever loses focus for some reason, regain it by pressing Ctrl-F12
Finally open any file in your project using Ctrl-Shift-r
Edit from anula comment:
A useful thing to mention here: Ctrl-w by default binds to closing window, so if you want to use it as in Vim you need to first go to Window->Preferences->General->Keys and unbind "Close".
You can install the HandySplit plugin from Eclipse Marketplace and bind its 'Toggle focus between split editors' command to any keyboard shortcut you like.

Ctrl Space Not Working in Eclipse Helios on Win 7

I have shifted by Dev Env recently to Eclipse Helios on Windows 7. After that the Ctrl + Space Content Assist feature is not working. I found out that that key option is utilized by Language Settings. I have tried disabling it. But it still doesn't work in Eclipse.
Any help is much appreciated.
Configure Eclipse’s content assist, go “Preferences>Java>Editor>Content Assist>Advanced“. Make sure “Other Java Proposals” is ticked.
http://www.mkyong.com/java/content-assist-ctrl-space-is-not-working-eclipse/
In my case nothing happens after pressing Ctrl+Space. Right now I have set a different short cut for the same and solved
Check your "Keys" preferences: maybe the Content Assist" shortcut has been overridden by another command which would also use Ctrl+Space.
That could happen with the installation of a new plugin, coming with its own set of commands and shortcuts: the bug 303894 for the XText plugin is a good example.
You probably have another application (in systray) that uses Ctrl+Space for something else. In my case I have a small utility which when I press Ctrl+Space makes the active window on top.
The solution for you would be to (1) exit that application which overrides the keys or (2) in Eclipse change Ctrl+Space to some other set of keys.
This was solution for me to get rid of windows key shortcuts:
Go to Start > Type in regedit and start it
Navigate to HKEY_CURRENT_USER/Control Panel/Input Method/Hot Keys
Select the key named: 00000070 for the Chinese (Traditional) IME -
Ime/NonIme Toggle hotkey 00000010 for the Chinese (Simplified) IME -
Ime/NonIme Toggle hotkey
In the right sub-window, there are three subkeys. Key Modifiers
designate Alt/Ctrl/Shift/etc and is set to Ctrl (02c00000). Virtual
Key designates the finishing key and is set to Space (20000000).
Change the first byte in Key Modifiers from 02 to 00
Change the first byte in Virtual Key from 20 to FF
Log off and log back on. I don't think it's necessary to restart.
Do not change the Hot keys for input languages in Control Panel,
unless you want to do this all over again.

I have seen a similar problem in Eclipse Juno (version 4.2.0).
Since you have already tried Eclipse/Java code completion not working, I would check to see if there are any key conflicts. Go to Window -> Preference -> General -> Keys. In the filter box, replace the light gray "type filter text" with the word "Content"; the first item should be "Content Assist." Select it. It should have nothing in the Conflicts box in the lower right-hand portion of the screen.
If you have no conflicts, then it is likely that there is another program, outside of Eclipse, that is binding to Ctrl + Space.
I worked around this with an ugly solution. I copied the Content Assist. In the Binding field, I entered held down the Ctrl + Alt keys and pressed space. This restored the Content Assist function, but it required a brain remap when I am using one machine.
!Screenshot of Eclipse Juno, I had the same problem, then I changed it to different key combination, then it works.1
This is what solved my problem.
Goto Control Panel -> Clock, Language and Region -> Change keyboards or other input methods -> Change keyboards... -> Advanced Key Settings. For some reason I had ctrl + space set as Key sequence for language hot keys. I changed them to something else and rebooted.
Make sure to reboot because it did not work for me without the reboot.
On my Ubuntu, Xfce, ctrl space was allocated to switch language on the iBus preferences (if you have this running, you will see the 'i' icon on the task bar, right click and choose preferences). To change this, bring up the IBus Preferences, on the General tab, see the "Enable or disable:" option, click the ellipses and provide a different keyboard assignment.
This sorted me out without need to restart Eclipse.
I use eclipse indigo and had this problem. Creating a new workspace did not worked.
Go to Windows->preference->General->Keys->"Restore Default" - This fixed my issue
Note that I just had English(US) on windows 7 [Control Panel-> Clock,Language and Region ->Change keyboard or other input methods-> Keyboards and Languages->change Keyboards...->General ==>Default language is English and Installed Services I just had English(US) alone
After doing this some you might need to restart the system if it does not fix.
This is how I fixed my problem on Ubuntu 12.04 regardless of the eclipse version. My problem was that the ibus was overriding the shortcut so I deleted this shortcut configuration.
Type ibus in the dash:
Then select Keyboard Input Methods. From there click on the first three dots next to the Enable or disable textfield. This windows should appear:
If there is something bound to Ctrl + Space simply delete it.
#Polac - Thx. That's what fixed it for me. I'd hit ctrl+space and I'd get a popup for chinese character selection. I have Windows 7 so for me it was:
Control Panel -> Region and Language -> Keyboards and Languages tab -> Change keyboards... button -> Advanced Key Settings tab
Be warned, its stubborn. I tried to just clear them, but as soon as I applied the settings they reset back to using the original key bindings. If I change the key binding to something obscure they still reset sometimes. It's annoying. Maybe its just my OS installation that's goofed, but it could be a Microsoft bug.
Didn't need Chinese on my system, so I removed it as an installed language in the first tab and that finally got rid of the hardcoded Chinese key bindings.
In Eclipse you can use the Alt-/ character sequense instead of Control-Space. This is an old problem which Eclipse and Chinese keyboards, which they addressed by adding this short cut.
I found the answer.
Windows / UV Elements - was OFF! I don't know how but they were off. And when you click Ctrl+Space he working, but your all elements are off and you think that it is not working. You must on all UV elements and after your Ctrl + Space will be work.

How can I indent a selected block of text in Eclipse 3.5.2?

I use TAB and Shift-Tab in Visual Studio to indent an entire selection. This does nothing in Eclipse, and I can't seem to find another way to do it.
Update: I wasn't really paying all that much attention to this initially and did not ask the question correctly.
I now realized that it is in XML files where TAB still does not indent a selection. I did not find a setting for this in the properties, so I assume it is not possible.
Tab and Shift+Tab are the normal ways to do this in Eclipse, just like in Visual Studio.
In addition to the keyboard shortcuts, you can also do this from the Source menu. Source -> Shift Left, and Source -> Shift Right.
Have you checked to make sure tab/shift tabbing is working as you expect in other applications? Is there a stuck key on your keyboard preventing the shortcuts from working? Could another application be stealing the keyboard shortcuts? (as odd as that sounds...)
Also, try restarting Eclipse.
ctrl + i ---> it is for making accurate indentation to a block of source code.
Go to Window Menu -> Preferences -> Java -> Editor -> Typing and make sure the `'Tab key adjusts the indentation of the current line' checkbox is ticked.
