Is there any way to use camel case navigation? For example, if the cursor is before the word HttpServlet hitting Ctrl-left would stop between Http and Servlet instead of after the whole word?
No. I suggest to increase the keyboard repeat rate to move more quicker right or left. The default keyboard repeat rate setting is very low, but should be increased, if you have enough keyboard experience.
