Anyone has an idea what's going n here ??

Try this
Check whether multiple commands are registered for Ctrl+Space short cut.
Go to Windows->Preferences and in search box type keys and check. It should be shown as below.
If multiple commands are registered then change the other key bindings short cut other combination of keys.

Custom Eclipse Shortcut doesn't work

I'm trying to attribute a custom shortcut key in Eclipse Kepler. It's for the Base from Working Copy in the Compare context menu any give file (via right click). This screenshot shows how it's been setup:
Pressing that key combination does absolutely nothing. ATM, other Compare sub menu commands are working fine (ie. CTRL+ALT+L). When I right click on a file > Compare, I can see the assigned shortcut in the context menu.
I've restarted Eclipse after assigning the shortcut to make sure it "takes" properly. Still to no avail.
It may be because of other commands also registered for the same short cut i.e Ctrl + Alt + L.
Please do verify how many commands are registered for the short cut Ctrl + Alt + L, by typing the "CTRL+ALT+L" text in the search box below the Scheme combo box.
If multiple command are registered then change the short of your command so that it become unique, then try the command and verify the result.

Eclipse double click scope selection and Alt+shift+up not working after installing aptana plugin

Double click for scope selection and Alt + Shift + ↑ were working fine before installing Aptana Studio plugin, but now both are not working. Is there any setting to enable it again?
I'm using Eclipse Kepler Service Release 1
There may be key conflicts occurred between original short-cuts and with the Aptana plugins.
Go to Window->Preferences. Type keys in the search box. Type Shift+Alt+Up in the keys preference page search box. If there are multiple commands registered then check the context of all these commands or assign new short-cut key.
!How to do this!
As you see in the picture. For Alt+Shift+Up keyboard short-cut multiple commands are registered. Change these short-cuts and make them unique.Click on Binding text box, delete the content and Hold your Ctrl key and Press 0.
Make sure that this short cut is not assigned to any other commands.
Now you can do selection scoping using the new short-cut i.e Ctrl+0 while editing java source.

How to enable "live search" in eclipse?

In Komodo Edit, an input field is available in the toolbar. When I type text in it, it highlights matching search results. Is there something like this in Eclipse, either directly or via a plugin?
As TK Gospodinov has already mentioned, there is an Incremental option in Find/Replace (Ctrl+F) dialog.
There is also a special key binding for Incremental search in Eclipse (and personally I use it more frequently). From Eclipse Tips and Tricks:
Use Edit > Incremental Find Next (Ctrl+J) or Edit > Incremental Find Previous (Ctrl+Shift+J) to enter the incremental find mode, and start typing the string to match. Matches are found incrementally as you type. The search string is shown in the status line. Press Ctrl+J or Ctrl+Shift+J to go to the next or previous match. Press Enter or Esc to exit incremental find mode.
If you'd like to have search functionality in a toolbar, you may be interested in the eclipse-glance plugin, which allows you to use the incremental search function in a toolbar by pressing Ctrl + Alt + F while in any text area.
This feature is already available in eclipse. No need to install any plug-in.
Press Ctrl+F, and the Find pop up appears.
Now check the incremental checkbox, and then your texts will be found as you type. No need to hit return.
OR
Use Ctrl+J and you can activate the live search, just that there wont be any UI visible, but you can see the status in eclipse status bar at the bottom.
Press Ctrl+J, start typing the text you want to search for. Press esc to go back to edit mode
The closest thing to the functionality you are asking about is the 'incremental search' mode, which is triggered by checking the 'Incremental' checkbox in the Options group on the Find/Replace dialog in Eclipse (Ctrl+F from the code editor). This will make it start highlighting matches as you type, and if they are keywords, Eclipse will highlight other occurrences (references) in the code editor. Matches inside strings or Javadoc will not be highlighted, however, unless it happens to be the first match after your cursor's position inside the editor.
One similar thing (not the same) is just enabling "mark occurences", then selecting function name, variable etc.

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.
