Finder shortcut for creating a new empty file

Every now and then, for various reasons, I find myself wanting to add a new empty file to a folder. In the Windows world this is easily done through the context menu, i.e. right click→New→Text Document, but I didn’t have any neat way of doing it in Mac OS X Finder (without opening up Terminal to run “touch newfile”) – until I found this: http://www.codium.co.nz/touch%5Fhere%5Fapp/.

It works really well! For times when I want to have a bit more of “text beauty” I can create a file, open it in TextEdit and simply convert to Rich Text.
