[SC.LUG] Keyboard shortcuts in Ubuntu

[Matthew Tolley]

Hello all,


Since upgrading to Ubuntu 12.04 around a month ago some of my often-used 
keyboard navigation shortcuts no longer work.

Zooming in or out using Ctrl and + or - no longer works, but far more 
annoyingly my favourite shortcut of Alt+Tab to switch between windows or 
applications also no longer works.

All these shortcuts seem to be set up correctly in my System Settings 
(as far as I can tell) and some shortcuts (which I hardly ever use) seem 
to work fine (such as Ctrl+Alt+Shift+left or right to switch between 
workspaces). The non-functioning shortcuts also work fine when I run 
another OS on the same machine, so that rules out hardware faults.

A brief search of Ubuntu forums suggests I am not alone, but instead of 
Ubuntu fixing the issue at source there are a wide variety of differing 
workarounds which mostly go above my level of technical knowledge.

Could someone assist me with a fix for this which is simple enough that 
my non-technical brain can cope with?

Many thanks,



Matthew Tolley
