Problem with eclipse text editor - eclipse

Does anyone ever have problem like this??
The "Enter" , "Tab" , and "space" character is shown .. and I don't know how to fix it. I have tried to restart the Eclipse, change the Android SDK, and also restart my computer. but nothing seems to work. everything stays like that. It's not a relly big problem, but it feels really annoying to see all those character floating around.
anyone have solution?

In the preferences, go to General > Editors > Text Editors and disable "Show whitespace characters". I'm sure you pressed some kind of keyboard shortcut to enable it in the first place.

Visual Studio Code: How not to show suggestions on space?

So anytime I type space it brings up suggestions, which causes problems when I type space at the end of a line (just because i like having a little space there. This way cursor is at some distance from code when i click at the end of a line, it's easier to see code, it's less cluttered), and press enter. It brings up suggestions menu and insert the first thing from there, while i just want to insert a new line character.
I also need it to show suggestions when I'm typing, but only when I type a non whitespace character, so I can't set it to not bring up suggestions on typing.
I also want to accept suggestions on enter, so I can't turn this off either.
So I'm stuck with wanting suggestions on typing, but not on space, is there a way to somehow exclude space from suggestion triggers?
You can customize how you want to display it, this feature is called IntelliSense.
Go to File > Preferences > Keyboard Shortcuts (MacOs Code > Preferences > Keyboard Shortcuts)
and you can set the new key on:
list.toggleExpand
notification.toggle
if you want advance settings, go to keybindings.json
more info:
https://code.visualstudio.com/docs/editor/intellisense
https://code.visualstudio.com/docs/getstarted/keybindings
I think i've found a solution: turn off Suggest on Trigger Characters option.
This way it doesn't bring up IntelliSense on space or dot or anything else, but it still brings it up when i'm typing ordinary characters

Eclipse Find/Replace not working

I have searched for a solution to my problem but with no avail. The eclipse Find/Replace function found by the hotkey ctrl+F is not working. Note: the function does not work by the hotkey neither by going through Eclipse menu Edit>Find Replace (not working I mean that the FindReplace window does not show at all, the eclipse window loses focus only). I have tried to disable the hotkey to see if it would work, restarted eclipsed, restarted the PC, but nothing seems to solve the problem. It was working just fine but then suddenly out of the blue it just decided not to function anymore. Everything I tried so far has failed. As I use this function often it would be nice to know if someone has another input for trying to solve this bug. I am on a PC with windows 7, intel i7 64-bits.
I had a similar issue after using second monitor at work. At home I was wondering where is my Find/Replace window... it was displayed at the second monitor as I used it last time... Eclipse stores the last location of the dialogs for better UX.
So try to move the Find/Replace window by using your keyboard.
How to Move an Open Window with the Keyboard
You can also try to reset perspective
Window > Perspective > Reset Perspective...
I had the same issue with Eclipse. My current version is Neon.3 Release (4.6.3).
This periodically happens where the Find/Replace does not work.
Usually UNDO stops working also.
When this happens, Ctrl+F, Ctrl+Z do not work, and Undo Text Change and Find/Replace... are grayed out in the menu.
I tried the above solution Window > Perspective > Reset Perspective...
That fixed it right away!
Thanks
When your Eclipse are full with cache that time this problem occurs.
please try to reset perspective setting and then check it.
Just go to menu bar : Window -> Perspective -> Reset Perspective and it will done.

How do I turn off Tab and New Line markers in Eclipse?

I am using Adobe's ColdFusion Builder, an Eclipse-based IDE built on top of Aptana.
All of a sudden, I am getting a type of whitespace marker showing in my Eclipse Editor. I must have accidentally hit a key combination.
Here is a screen dump.
I have already tried "General > Editors > Text Editors > Show whitespace characters" and it is not this. I already have show whitespace characters turned off. If I turn it on, then the Whitespace Characters display over the top of what I am already seeing.
Can anyone tell me how this can be turned off? Most annoying.
Many Thanks
It's under Preferences -> General -> Editors -> Text Editors
Just uncheck 'Show Whitespace Characters':
Did you try Restarting Eclipse? If that didn't work, you might try this http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.faqs/ka11640.html which explains which file to delete to force eclipse to revert to use default settings.
I have done this several times by accidentally hitting some keystrokes.
If you go to Windows/Preferences/General/Keys you will see all the keyboard shortcuts you have.
Mine is set to Control + .
(that's a period by the way) I had to place my cursor inside the document and do it a couple of times to make it work because there is also a keyboard shortcut for Control +
On a Mac it is Cmd +.
Hope that helps.

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.

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.

Keyboard shortcut to fix error in netbeans

Whats the keyboard shortcut to open the list of possible solutions to an error. The button is to the left of an error and looks like a little light bulb. I would like to use this without reaching for my mouse.
The default Shortcut is Alt+Enter. It is also accessible in Source/Fix Code.
