How to make Chrome reload all JS and CSS file of a page?

It is known that using shift+ctrl+R can be used to force chrome browser to reload the page instead of reading from cache. However, while the images are reloaded, the JS and CSS files are not loaded. Currently I have to test my page on incognito mode, close and reopen the incognito tab so as to make sure the page is not using the cached JS and CSS files.

Is there any settings or hotkey I can do this in normal mode? It is really tiring to reopen the windows every time I need to test the changes in CSS or JS files.
