Hello, Codeforces!

I've been watching videos of top competitive programmers like tourist, and I noticed that they navigate through their code extremely fast without using a mouse. For example, in this video:

tourist coding session ICPC 2017

It seems like he can: 1. Jump between lines instantly 2. Move through words efficiently 3. Switch between files effortlessly 4. Manage compilation and execution without ever touching the mouse

I'm currently trying to improve my keyboard-only workflow for competitive programming, but I'm not sure what the best techniques and shortcuts are. My Questions:

1.What keybindings or tools do you use to navigate code quickly? 2. How do you move between functions or specific parts of the code without a mouse? 3. Are there any plugins or editor settings that help with this?

What is the best setup for Far Manager? — that's the main question (i want to be like tourist)

If you have any tips, tricks, or resources, I would really appreciate them!

Thanks in advance, and happy coding!
