Started Vi finally.

Vimtutor is a great way to learn Vi, especially for beginners who want hands-on practice.
One of the most memorable tips is that the j key moves the cursor down, resembling a down arrow.
Navigating with h, j, k, l quickly becomes second nature, making movement in Vi efficient. Commands like
A for appending text,
x for deleting a character,
dw for deleting a word help streamline editing.
Mastering these basics sets a strong foundation for efficient text manipulation in Vi.
