I don't know what the hotkey I accidentally clicked, but this Ǧ looking sign appeared on every line of code, and there are grey dots instead of spaces in the code.
How can I get rid of those characters?
Assuming this is SQL Developer, go to Tools->Preferences (or on Mac, find that under the SQL Developer menu). Expand the Code Editor section and click on Display. Untick "Show whitespace characters" (second checkbox in the list).
You can check for defined shortcuts under Preferences, in the Shortcut Keys section. On Mac there isn't one for this, but Windows has it as Control+Shift+W, which will also toggle them off if you don't want to go through the preference pane.
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.
I'm trying to switch from Komodo to Eclipse.
I can't figure out how to keep line-break characters from being shown in eclipse - looks like they are shown along with tabs and other whitespace characters.
Is there a way to show tabs and other whitespace characters but not line-break characters?
If you have Eclipse 3.7 you can disable them.
Preferences > General > Editors > Text Editors -- Look for 'Show whitespace characters' and click on the link 'whitespace characters'.
Or you can directly click on the shortcut:
In the Luna version, this configurability is now called "configure visibility" under "Show Withespace characters"
In your Eclipse, go to:
Window --> Preferences --> General --> Editors --> Text Editors
Click the highlighted link (configure visibility) in the check-box SHOW WHITESPACE CHARACTERS and select the check box as per your requirement.
Somehow I've turned on hidden characters in Eclipse. It's not the "whitespace" characters in the general editor preferences. When turned on, it adds another layer of hidden characters over the existing ones.
Then I have things like
\r\n
Does anyone know what these are and how to remove them?
It is under Preferences > General > Editors > Text Editors. There is a checkbox labeled "Show whitespace characters". If you uncheck this the editor switches back to normal.
If you click on the link (whitespace characters) (<= v3.6) or (configure visibility) (>= v3.7) in this line you will get a popup window, in which you can define which characters eclipse is supposed to consider as whitespace characters.
In this popup window you also get the option to define the transparency in which each whitespace character is displayed in the editor, which you can use to (indirectly) change their foreground colour. I'm just mentioning it here, because it took me about half an hour to find this setting! ;-)
There is a toggle button 'Show Whitespace Chars' on the Eclipse toolbar
A great tip about using 'quick access' from eclipse forum:
CTRL+3 swc
Allows to turn them on and off
The right shortcut is Ctrl + N
UPDATE From Eclipse 3.7 version, something is changed... Now you have to go to:
Window > Preferences > General > Editors > Text Editors
CTRL + . does the job.
For Aptana Users
To toggle hidden characters in Aptana on and off, use the following keyboard shortcut:
Ctrl+Alt+W
I am using Eclipse Oxygen and can see this option to toggle whitespace characters:
It is actually in two places...
Sandkastenliga points out the obvious one, but you can also show white space with a shortcut key combination. The key combination is separate from the text editor preferences and will superimpose additional characters when active (it uses \r and \n for carriage return an line feed respectively instead of the symbols used by the text editor preference.)
Go to preferences > general > keys and look for the binding for the 'Show Whitespace' command.
I have the text editor preference turned on, so I removed the binding for this command altogether (it was set to Ctrl+. in my profile) to prevent accidental activation as it doesn't affect the other preference.
Go to Window > Preferences > General > Editors > Text Editors
Uncheck the "Show whitespace characters" option on the right side of the page, then click "Apply" at the bottom of the page.
Since this is not a standard setting, it could be the result of one of your extra plugin.
Did you try starting your eclipse with the -clean parameter?
Do you reproduce the issue with a fresh Eclipse installation?
Go to Preferences > General > Editors > Text Editors and restore defaults.

You can add "Show Whitespace Characters" button in toolbar by customizing your perspective.
It also contains buttons to toggle word wrap, and toggle selection mode.
Go to Window > Perspective > Customize Perspective > Action Set Availability, then select "Editor Presentation" action set:
This works in Eclipse Neon.
You can also add a key binding for this action.
Go to Preferences > General > Keys > "Show Whitespace Characters"
Sorry this is a bit vague but it's a while since i used Eclipse and i do not have it installed. I think this is it ..... in one of the menus you will find the Eclipse settings, there are two set's of settings, current project and overall Eclipse, you mat need to check them both. In there are various menus in tree form that allow you control the actions and look and feel. But some of them are nested so there is an overall control but some packages have their own options in a sub menu set. The menu's will expand when you click them and i'm afraid you need to walk through them all.
Eclipse > Preference > General > Editors > Text Editors > Show WhiteSpace characters.
I need to view the tabs and spaces and CRLF in python source code in eclipse the same way we could see them in notepad++, Now I have to edit in notepad++ and run in eclipse. Not a neat way but eclipse does regular update of the changes of same file in other editor.
This should be cover with the "Show invisible" option
From Eclipse3.3:
It is now possible to see the invisible whitespace characters in textual editors:
This feature can either be controlled via "General > Editors > Text Editors > Show whitespace characters" preference, or via the tool bar button when the Editor Presentation action set is enabled.
I did not tried it with PyDev, but its editor should be a "textual editor", and the option should work.
when I press TAB it creates spaces instead of >> for tabs
Check the option "General > Editors > Text Editors > Insert spaces for tabs":
if unchecked, it will display tabs, not space.
