The best way to do what, exactly? After editing a file, if you type Make,
that is the only way to rebuild (and also the best!)

If you read the code, and understand it, and understand how to make the
changes you want, then that is what you need to know. If you don't
understand the existing code, then that is what you need to know..
In essence, if you put together a bunch of functions, include statements,
for loops, while loops, if statements, and a couple of other things like
assigning values to variables, you can write 90% of Rockbox. But only if
you understand how to string them together in the right way. I'm not sure
what you mean by "what do you need to know in C". C is just a language, if
you know how to use the language then you can write code in Rockbox. But
there is no manual that describes 'which piece of the rockbox code you need
to look at to do some specific new kind of development that you want to do'.
You can only really get that knowledge by doing it. If you understand how
to read source code, how to write source code, how to understand the flow of
a program, and what the main utility functions do (e.g. lcd_xxxxx as already
mentioned), then that's all you "need" to know in C.

Try searching the source code - for example, search for 'bookmark' to find
source code related to bookmarks, and search for 'playlist' to find source
code related to playlists.

Make sure the editor you use preserves the line endings of the original
Unfortunately you don't say what text editor you are using, maybe it isn't
designed for programming?
Personally I use jmacs on cygwin. I would avoid a Windows-only text editor
such as Notepad since these will change line endings whenever you save the
