Is there any tool equivalent to spotlight search in OS X for Ubuntu 12.04?
Something where you just type a search string and files, folders or installed programs will appear in a list.

Synapse is a GUI tool which does exactly what you expect from a graphical program. It is a place where you just type file name, folder name or installed program name and it will appear in the list as shown in the next screenshot:
After installing you can configure your key bindings which you can use to invoke Synapse in order to write what you wish to find. It may require a certain amount of time in order to get the list of files and applications for the first use but it will improve as you use it.
