How to setup far manager for c++ competitive programming?

I searched entire web. Couldn’t find anything worthwhile. I’m in utter confusion.
Anyone using far manager please help.

Have you seen this? Far Manager as IDE - Codeforces

Yes! didn’t help… couldn’t get it working

What about Geany? which is also a good IDE for competitive programming, I am just curious that what the difference between Geany and Far Manager so that I can make a decision to use Far Manager if it is better than Geany.

This tutorial was really helpful to simply set it up for C/C++ ( for compiling and running and simple stuff )
but can someone help me with changing default keys and adding a snippet etc for competitive programming .

This is the best tutorial I’ve found, it’s complete with all the keyboard shortcuts and all

Can anyone tell me how to add a custom snippet in far manager?
