Cannot switch between windows of the same application

I'm using Ubuntu 11.10 with Unity.

Switching between applications (Alt + Tab) works, but switching between windows of one application (Alt + ') doesn't. Tried to assign Alt + ' switching to another shortcut (Super + ', Ctrl + ', Alt + F1, using system settings) but nothing works.

After install, everything was working fine.

I have ' (apostrophe) instead of `. To get that, I edited files in the /etc/X11/xkb/symbols. Of course, if this matters.

Seems like there is a problem with assigning shortcuts using system settings. When I assign between windows of the same application to Alt + Tab, it still switches between different applications. No idea what's going on.

UPDATE: The problem is fixed. I've been changing different settings of my keyboard, and one of the settings changed was XKBMODEL. I set it to "latitude" (thought it would fit better, that was really stupid). After I changed it back to "pc104", everything worked normally again. Thanks everybody for your attention!

UPDATE 2: The ` symbol still needs to be in it's place for US layout. For Russian I was able to leave ' assigned to "TLDE" button.

UPDATE 3: Seems like I have got the same problem with "Switch between windows of the same application immediately" (which is Alt + Esc by default). It doesn't work, and assigning it to another shortcut doesn't help. Any suggestions?

This was my problem too. Alt+<key above tab> didn't work to switch windows in the current application.

In addition, when i pressed and held down the super key to see the unity shortcuts, normally one would see this:

I'm assuming that is for a US keyboard? I stole the screenshot from another post, and on my danish keyboard it now shows Alt + Onehalf.

But when I had this problem, I did not see the line pointed to by the red arrow!!!

So check if you see a keyboard shortcut for "Switch windows of current application". If you don't this is for you:

The fix was as hinted at above to change the XKBMODEL setting in /etc/default/keyboard where I changed from XKBMODEL="microsoft4000" to XKBMODEL="pc105".

I did that and ran sudo dpkg-reconfigure keyboard-configuration. Not sure this last step was required.

Then I needed to reboot.

Now it works.

Suboptimal, but you can use the down arrow after Alt + Tab.

You can change the short cut key of "switching windows" to Alt +Tab. Then you will be able switch between windows (not applications)

Exclusive for ubuntu 18.04 LTS - search keeyboard in settings and do the above change
