This is more of a social bookmark than a full article. OS X is pretty neat but the ever-present philosophy of “our way of doing it is the right way” can be frustrating from time to time. Since I do not really like the trend of paraphrasing already written articles I will just dump a bunch of links here and say what I used them for.
Home and End keys should go to the beginning and end of the line you are on while editing. In OS X they scroll to the top and the bottom of the current document, which is retarded.
I like keyboard repeat. Also I like to be able to copy text from QuickLook.
I use this for my side-project of making Midnight Commander actually usable on OS X. So far I did not have time to really invest into it.
