Lunarvim is a powerful tool that can enhance productivity for advanced software engineers. One feature that is particularly useful for working with multiple files is vsplit and telescope. However, it can become cumbersome to navigate between files using a mouse.
Easiest way is to use :bp command. However it jumps files sequentially.
First get the buffer number by typing :ls which will display buffer number corresponding to the filename.
Now to make a jump to a specific file
:buffer 2
This allows you to quickly switch to a specific buffer, without having to cycle through all open buffers using the :bn and :bp commands.
I mostly avoid using mouse and love to do most of my work using keyboard.
