Enlarge font size of function names in source code like Source Insight

Question

Source Insight can show function names in a larger font. Can Emacs display function names with a larger font and different color?

Answer 1

This can be done pretty easily.

press M-x RET customize-face RET font-lock-function-name-face RET and you'll get the customization menu for function name face. You can change any attribute you want(font weight, height, color, etc.) and don't forget to click on Apply and Save and save for future sessions.
