### How to use
If you want to perform file opreations (move, remove etc.) you have to select the entry / entries first. So if you want to remove `foo`, you have to move to it, and when its highlighted you have to press `space` to select it and then `r` to delete it.
The keybinds below will help you understand how the program works.
If you want to perform file operations (move, remove etc.) you have to select the entry / entries first. So if you want to remove `foo`, you have to move to it, and when its highlighted you have to press `space` to select it and then `r` to delete it.
The keybinds can be configured in `config.h`, that will help you understand how to navigate the program.

### Config
Edit `config.h` then just recompile the program via `make`.
