I've been using Snow Leopard 10.6 for years until I recently bought a new Macbook Pro with Mavericks 10.9.4 and am trying to customize it in order to retain the same workflow I'm used to. A couple of things I haven't figure out: In Snow Leopard I could press F4 (on my extended Apple keyboard connected to a Mac Pro) to access widgets. If I do this on my Macbook Pro with Mavericks I instead get the launchpad. I can't find and entry for F4 anywhere in the "Keyboard"-"Keyboard shortcuts" system preference, so is this somehow hardcoded and un-editable in Mavericks? I love Exposé, but alas it's no longer in Mavericks though I have gotten it to behave in much the same way. In 10.6 I had a hot corner for "All windows" and "Desktop". In 10.9 I have a hot corner for "Desktop" but there's no "All windows" so I chose "Mission control" in its place with the "Show Dashboard as a space" feature turned on. It's more clicking than with 10.6 though. Is there a better way to access the Dashboard (if F4 can't be redefined)? And is there a way to get a hot corner option for "All windows" back?
