How to execute a Ctrl+,,f keyboard shortcut in Sublime Text?

Question

I am trying to execute a keyboard shortcut noted as Ctrl+,,f The shortcut is meant to evaluate a script by sublimeREPL in Sublime Text 3.

What exactly should I press on the keyboard? I tried holding Ctrl and then pressing the comma key two times and then the f key. I also tried holding all the keys, but I every time I try, I get the find box triggered.

What am I missing here?
