While using 10.04 and the previous versions I used to put Ctrl+F6 to zoom in and subsequently Ctrl+F7 to zoom out. Now I can't even find the options to zoom in and zoom out in the "keyboard shortcuts". I tried "the Magnifier" in the Compiz but really can't understand what is going on right there. There is simple question I would like to ask:

What to do so as to be able to zoom in with Ctrl+F6 and zoom out with Ctrl+F7?

Thanks a lot.

welcome to ask ubuntu! you forgot to tell us which version of ubuntu do you have. 11.10? and with which DE? (unity, gnome shell KDE... etc) – suli8 Nov 24 '11 at 18:37
Yes 11.10 Unity. Sorry for wasting your time. I eventually figured it out. Since today I am using 11.10 and everything is so different to me. – stanimir Nov 24 '11 at 18:45
Accidentally I pressed Super+D and magnifier feature start in my ubuntu 13.04 . For zoom in only. I don't know for zoom out. – Akatsuki Apr 17 '14 at 7:12

Open Compizconfig Settingsmanager.

Go to Accessibility / Enhanced Zoom Desktop.

Click on the "Disabled" titled Button of Zoom in, click on enable, grab key combination and press ctrl+f7. Do the same for Zoom out, and you are set. Screenshot:enter image description here

Thank you for the quick answer. Love you Ubuntu guys. – stanimir Nov 24 '11 at 18:54
so the enhanced zoom is disabled by default in Oneiric and PRecise? And does it work fine when enabled? – MestreLion May 18 '12 at 19:47

Other than the Compizconfig Settings Manager, a new configuration tool is now available called Unity Tweak Tool.

Open Dash (by tapping on Super) and type "Unity Tweak Tool".

Unity Tweak Tool in Dash

If it is not available, you can install it from the software center (Unity Tweak Tool Install Unity Tweak Tool), or you can install it from the terminal with:

sudo apt-get install unity-tweak-tool

Open the application, and from the icons choose General under the Window Manager section.

Unity Tweak Tool Main Window

Once you click General, enable the "Desktop magnification" option at the top. And you can change the default keyboard shortcuts of the Zoom In, and Zoom Out functionalities.

As seen in the next screen-shot, I have the Zoom In set to Ctrl+Super+Z and the Zoom Out set to Ctrl+Shift+Super+Z

Personally, I prefer including the Super key to all system wide shortcuts so it won't interfere with a certain application's shortcut.

CtlShift- to reduce
CtlShift+ to increase

I found you also need the + from numerical keypad not the one next to the backspace button

On a laptop with no numerical keypad, seems to be just ctrl + +/- (need shift anyway to get +) – Zanna Jun 23 at 6:28

It is worked for me.

CTRL + + will Zoom In.

CTRL + - will Zoom Out.

Thank you.

C-+ and C-- are simply passed through to the client window, and many applications, e.g., Google Chrome, interpret it. Hence it "works" in that that one window zooms. But they don't affect the screen-level zoom, where the pixels get magnified (hence the screen appears fuzzy), and moving the mouse pushed around the image. – Quigi May 26 at 14:30
