How to enable this eclipse scroll bar? - eclipse

When editing Python code I get this scroll bar (even in Java perspective):

I have installed the PyDev plugin which gave me this bar but is it not possible to use it for Java?
I would like to see this when editing in Java rather than the standard Window's style scroll bar
but I don't know how to enable it or even what it is called.
Does anyone know?

This is the PyDev 'Overview Ruler Minimap'.
It is solely a feature of the PyDev plugin and is not available for other languages.

Is it possible to half-page down and up in Eclipse?

I have been trying to scroll half-page down/up within Eclipse (in Windows). Checked key-bindings but found nothing there. Is this possible in Eclipse with a short cut key? If it is not possible then can I integrate this with a plugin?
Out of the box, there is no defined function that will scroll up/down a half page. I'm not aware of a plugin that provides this. One plugin that provides several functions related to navigation (and many others) is Emacs+, but that also does not provide any "half-page" navigation options.
Self answering after a long time.
This is possible with Vrapper (Vim-like) plugin for Eclipse. It is basically bringing Vim environment in Eclipse but without breaking any existing Eclipse functionality.
Same shortcuts in Vim is valid also for this plugin.
CTRL+D is half-page down.
CTRL+U is half-page up.
Before using Vrapper keyboard shortcuts, make sure you unbind those keys from Eclipse.

Is there a way to programmatically change the color of an editor tab in my Eclipse Plugin?

I have a SharedHeaderFormEditor in my Eclipse RCP plugin.
One of my requirements is to draw attention to the editor's tab when something happens outside of the editor and it needs a refresh.
Some of the ideas discussed included
changing the color of the tab
adding an icon to the editor's text (instead of the standard * for a dirty editor)
Are either of those possible? I've been looking around and have not found anything that could address this issue.
Thanks!
ViewPart and EditorPart both allow changing the title label and icon (setPartName(…) and setTitleImage(…) respectively). The Eclipse Workbench also offers an IWorkbenchPartProgressService to each part, which allows a part to indicate that it's busy (via incrementBusy()/decrementBusy()) and that its content has changed (via warnOfContentChange()). You can see this used in the Search and Console views (org.eclipse.search2.internal.ui.SearchView and org.eclipse.ui.internal.console.ConsoleView).

How do I get rid of this toolbar in Eclipse?

How do I get rid of this toolbar shown in the picture? I fatfingered some keys and now I can't get rid of it, primarily because I'm not 100% sure what it is...
This is in the normal Java perspective. I've tried resetting the perspective, but that didn't work.
The annoying toolbar you're describing is called the Java Editor Breadcrumb (see Eclipse documentation)
It can be disabled by pressing Ctrl + 3 and toggling Java Editor Breadcrumb
That's the breadcrumb bar. It shows the details of the location of the class you're currently editing. It's useful to quickly see if you're editing the correct class, and you can use it to navigate to other locations in your project as well.
If you want to turn it off click this button in the toolbar:

Eclipse presentation mode

Is there a plugin which supports for presentations in Eclipse ?
That means, assume the code is required to present for a couple of people and if the code is showed as it is, all tools, menu bars and all other icons are shown. Instead, I want to show only the tab which code is open (it can be a class,html or css file) in a full screen so that the PC can be connected to a projector and whole audience sees the opened tab only.
I have seen this in IntelijIdea, but not in eclipse. Any Suggestion please? I use Luna.
Maximize the tab and Ctrl+ (on Eclipse Neon)
The most recent version of the saneclipse plugin has a full screen mode.
You can use Ctrl+M which will maximize an active view or editor.
Also, use Alt+F11 for toggle full screen.

Overview bar in Eclipse Classic

I am having a strange problem with Eclipse Classic Indigo where I cannot see the overview bar. I did some searching and could not find any option to enable or disable it, but it appears to be disabled in my Eclipse. I was wondering if anyone had a fix for this?
DOH! New Mac User having a windows moment -- I have the answer to this question. I was looking for the top menu bar INSIDE the eclipse dialog (i.e. just above the icons) but like everything else mac it locates the top menu bar outside the actual dialog at the top of your monitor view.
Hope this helps someone else :)
