after being away from ubuntu for a while and being used to an inverted touchpad scrolling, I have recently jumped on ubuntu 13.04 bandwagon again. I have being having a hard time and am wondering if it is possible to invert?
Ubuntu has been crashing on me recently. I think its because it runs out of memory so I ran the free -m command and found that my memory usage was really high. So then, i ran top to find the culprit, but the displayed processes were using less than 1.5% of memory. How do I know which program is making ubuntu crash/run out of memory? Below is the output:

Or is it normal to have 110mb of free memory and is my issue related to something else?
While I have a nautilus window open I can do Ctrl+Shift+N to create a new folder in the current directory. However there is no default keyboard shortcut for creating a new document. How would I create one?
