Fun fact: If you use muscle memory, coming from a German non-Mac keyboard layout to a Mac keyboard layout you'll end up constantly closing applications. The combination for @ on non-Mac keyboards is AltGr + Q and on Mac is Alt+L. Now if you use your left hand to type @ the AltGr key is roughly where the Command key is on an Apple keyboard. Thus you end up pressing Command + Q: quit. It's great fun when adding additional recipients to a lengthy email you are writing. Thank god for auto save and terminal buffers.
