Eclipse shortcut CTRL+M behavior - eclipse

In eclipse we have the ctrl+m shortcut for maximizing windows.
But when you have two editors opened side by side, it maximizes both editors.
Is there anyway to change the default behavior of ctrl+m so it only maximizes one window?
(Personally this is the behavior i need 9 out of 10 times using ctrl+m)
Thanks.

you can enable this by changing your presentation preference. normally maximizing single editors is not possible (since 3.2 the maximize action is only available for views and the complete editor area, you can't maximize a single editor)
but how to change the presentation then?
click Window -> Preferences
in the preferences goto General -> Appearance, and the change the 'current presentation' to 'Eclipse 2.1 Style Presentation' or 'Classic' and restart eclipse. now you can maximize the editors on their own.

I don't want to change my eclipse' appearance into classic since I used to be with Dark.
So what I do is change the shortcut keys on "Preferences > General > Keys". You can define whatever you want from here.

Can Eclipse hold multiple different 'Compare' windows at the same time?

Like in the topic - is there any default way or any plugin that lets you have multiple 'Compare' windows open and active at the same time? I find it very frustrating that while doing changes to few files at the same time, I can't have active 'Compare' window for each of them, to see my changes/original code.
I would use Window -> New Window, rerun Team -> Show History and then compare another file.
A compare window in Eclipse is placed inside a normal editor tab.
You can have several editor tabs, including compare windows, visible at the same time. To do this just drag the editor tab (the one on the top with the editor name) to somewhere inside the editor area. The editor area will get split in two, each one displaying one editor.
This works with more than two editors also.
If you find that you need more space for the compare windows because other views take up much space you can maximize the editor area by pressing Ctrl+M while the editor area has focus.
Example:
Go to preferences -> team -> General Team Preferences. For me, the "Reuse open compare editors when opening comparisons" was already checked by default. I unchecked that and now I can have multiple file comparison windows open! (I'm using Eclipse Oxygen.3a -- 4.7.3a)

hiding the editor window form a perspective in eclipse

Once and for all, ban the editor (source code editor) windows from mingling my 'DDMS' perspective. How to do that ?
EDIT:

with the only available updates being for Mylin and Android something
You can minimize the editor area using a button in the top-right corner of the editor area. That let's you see that it's minimized in the window frame (along the right side) and easily Restore it.
Alternatively, you can set up a keyboard shortcut to really toggle the editor area visibility. Open the Preferences and navigate to General > Keys (or press Ctrl/Cmd + Shift + L twice to jump right to the Keys preferences). Search the commands for area and then assign a keyboard shortcut to the Toggle Editor Area Visibility command. Note: for older versions of Eclipse (3.5 and older), the command is named Hide Editors.
There is no way to permanently remove the Editor Area from a Perspective; that's fundamental to how Eclipse is designed.

Keyboard shortcut to change font size in Eclipse?

It is relatively straightforward to change font sizes in Eclipse through preferences (and answered several times in this forum).
However I'd like to change font size quickly (e.g., with Ctrl++ and Ctrl+- like in Linux terminal or Ctrl+mouse wheel in MS Office apps). Is there a way to do this in Eclipse?
Eclipse Neon (4.6)
Zoom In
Ctrl++
or
Ctrl+=
Zoom Out
Ctrl+-
This feature is described here:
In text editors, you can now use Zoom In (Ctrl++ or Ctrl+=) and Zoom Out (Ctrl+-) commands to increase and decrease the font size.
Like a change in the General > Appearance > Colors and Fonts preference page, the commands persistently change the font size in all editors of the same type. If the editor type's font is configured to use a default font, then that default font will be zoomed.
So, the font size change is not limited to the current file and the new value of the font size is available here Window > Preferences > General > Appearance > Colors and Fonts.
I know it has been long since the original question was posted, but for future reference:
check this project, https://github.com/gkorland/Eclipse-Fonts
I have used it, and it's very simple and efficient.
Take a look at this project: http://code.google.com/p/tarlog-plugins/downloads/detail?name=tarlog.eclipse.plugins_1.4.2.jar&can=2&q=
It has some other features, but most importantly, it has Ctrl++ and Ctrl+- to change the font size, it's awesome.
The Eclipse-Fonts extension will add toolbar buttons and keyboard shortcuts for changing font size. You can then use AutoHotkey to make Ctrl+Mousewheel zoom.
Under Help | Install New Software... in the menu, paste the update URL (http://eclipse-fonts.googlecode.com/svn/trunk/FontsUpdate/) into the Works with: text box and press Enter. Expand the tree and select FontsFeature as in the following image:
Complete the installation and restart Eclipse, then you should see the A toolbar buttons (circled in red in the following image) and be able to use the keyboard shortcuts Ctrl+- and Ctrl+= to zoom (although you may have to unbind those keys from Eclipse first).
To get Ctrl+MouseWheel zooming, you can use AutoHotkey with the following script:
; Ctrl+MouseWheel zooming in Eclipse.
; Requires Eclipse-Fonts (https://code.google.com/p/eclipse-fonts/).

Windows > Preferences > General > Appearance > Colors and Fonts
Then, to change Java editor font: Java > Java Editor Text Font > EDIT
There it is.
Oddly, working on a .js file and Ctrl, Shift, += works to zoom in (and Ctrl - works to zoom out but you have to select 1 or 2 after Ctrl -). This only works when I'm in the js file but the zoom applies to all my open tabs. Using Eclipse Juno on Ubuntu.
In Eclipse Neon.3, as well as in the new Eclipse Photon (4.8.0), I can resize the font easily with Ctrl + Shift + + and -, without any plugin or special key binding.
At least in Editor Windows (this does not work in other Views like Console, Project Explorer etc).
Found a great plugin that works in Juno and Kepler. It puts shortcuts on the quick access bar for increasing or decreasing text size.
Install New Software -> http://eclipse-fonts.googlecode.com/svn/trunk/FontsUpdate/
I use an Eclipse plugin (in Eclipse Marketplace)
https://marketplace.eclipse.org/content/fontsize
Here's a quicker way than multi-layer menus without resorting to plug-ins:
Use the Quick Access tool at the upper left corner.
Type in "font", then, from the list that drops down, click on the link for "Preferences->Colors and Fonts->General->Appearance".
One click replaces the 4 needed to get there through menus. I do it so often, my Quick Access tool pulls it up as a previous choice right at the top of the list so I can just type "font" with a tap on the enter key and Boom!, I'm there.
If you want a keyboard shortcut, Ctrl+3 sets the focus to the Quick Access tool. Better yet, this even automatically brings up a list with your previous choices. The last one you chose will be on top, in which case a simple Ctrl+3 followed by enter would bring you straight there! I use this all the time to make it bigger during long typing or reading sessions to ease eye strain, or to make it smaller if I need more text on the screen at one time to make it easier to find something.
It's not quite as nice as zooming with the scroll wheel or with a simple Ctrl+ or Ctrl-, but it's a lot better than navigating through the menus every time!

Eclipse: I turned on hidden characters now I can't turn off

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.
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 + .
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 +
Hope that helps.
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.

Turn off tooltips in Eclipse / Aptana

I don't know if anyone has noticed that Eclipse has this annoying feature where it needs to show a useless tool-tip when hovering just about anything.
I was wondering if anyone knows of a way to completely kill all tool-tip behavior in Eclipse / Aptana?
Thanks
I found mine in Window > Preferences > Pydev > Editor > Hovers
It looks like it's a module-level feature (Java, Pydev, C++), not platform-level (Eclipse itself).
Window > Preferences > Java > Editors > Hovers
Disable Combined Hover.
I agree, hints can be really annoying, but there are times when they can be a really useful quick reference - like finding var values during debugging, or required parameter types for a method etc.
So instead of disabling them altogether, or continually enbaling/disabling through the Preferences, I go to Window > Preferences > Java > Editor > Hovers > Combined Hover, and add Alt to the Pressed key modifier while hovering field below.
This way if you want to quickly see hints just hold the Alt key down.
I was completely annoyed with Aptana's tip tool text over my code. I figured out how to disable it:
Window > Preferences > Aptana Studio > Content Assist > Show information on hover > Off
I'm using Aptana 3.
Another thing which really annoys me on Eclipse are the light bulbs in the left part which hide breakpoints, and which are really useless.
To suppress these, go to windows>preference>java>editor and then uncheck "Light bulb for quick assists".
If you dont have this on your eclipse version, try a help search with "light bulb".
This is the answer. Change the Windows regedit.
HKEY_CURRENT_USER ->Control Panel -> Mouse -> mouse -> MouseHoverTime
Change its value to be 400 (4 seconds delay)
http://untamedmind.wordpress.com/2008/11/08/changing-the-mousehovertime-add-delay-on-the-tooltips-pop-up/
Look for TweakUI settings, under Mouse > Hover. Minimize the sensitivity and increase the time and you will, in most cases, be fine.
Note that this is under windows. In any case, search for "hover" and you should be able to find the correct location. Good luck!
