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?
