How do I move to the next capital letter?
When I searched for that I would be happy to just have the "native" solution: just enter in command mode:
/\u
which stands for "search for an uppercase letter". After that just move between capital letters with n and N (shift + n).
I would recommand the following script : camelcasemotion. It allows you to jump , delete inner 'camel case words', using ,+ normal navigation [w,b,e] etc...
