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?

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?
