[oXygen-user] short and long

Is there some way I can do an action and then assignment to a keyboard shortcut? I often capitalize letters that shouldn't be and on Frame and Word there is a keyboard shortcut to change it quickly. I didn't see such a shortcut in Oxygen (maybe there is?). I also see there is no way to record macros. I am using Linux and would like to record/create macros. How do I do this? Thanks?
