The combination for select all (Ctrl+A) doesn't work in a browser (either if we speak about firefox or chromium). It doesn't work if I try to clik in to the adress bar nor if I try to use it to select what I've written in google search bar at When I press Ctrl+A it simply takes the cursor before the first letter. This doesn't happen when I use a text editor software like Libre Office. There the shortcut does what's supposed to do, selecting all the text.

What could be the problem?

File it as a bug report, it works on my 12.04 system. – January Oct 29 '12 at 17:59
Did you enable Emacs style keybindings? – ijk Oct 29 '12 at 18:03
Also do you get the same problem from a freshly created user account? – ijk Oct 29 '12 at 18:04

Had the same problem in 12.10 and it was driving me mad. The problem seemed to be caused by using the Emacs key binding theme as described in the links given by others, except that according to GConf I was still using the default.

I realised that this is now set in DConf irrespective of the settings in GConf.

To change this open DConf and navigate to:

org > gnome > desktop > interface >gtk-key-theme

If the setting there is Emacs change it to Default.

Problem solved. For me at least.

Not sure what's wrong with your keyboard shortcuts, but this might help for Firefox; enter about:config in the address bar and then 'select' && the two options that can be useful are:



(Just set them to the opposite of default :))

I had this same issue happen in both Ubuntu 12.10 and Mint 13. The way I fixed it was by going in through ccsm and changing my themes back to defaults.

The Gtk+keybinding theme EMACs was the issue, when I returned it to default it fixed the issue and all other themes were working fine.

Use 'gnome-tweak-tool':

Ubuntu Tweak fix this problem for me, This is the update of tweak tools at the jan 2015 :

 -Tweak Tools -> Keyboard and Mouse -> Key theme -> set to : default
