Efficiency in File Editing with VIM

By changing the editing alias in VIM to a single letter like 'V' or 'E', users can significantly increase their editing efficiency. Previously using 'VI' for years, the shift to a one-letter alias has proven to be much quicker, as demonstrated in a YouTube video where one character was all that was needed to open the editor. This simple change has streamlined the editing process and is recommended by the speaker for improved productivity.
