Too Long; Didn't Read
Using the letters h,j,k, l, j, k and l keys to navigate a text file on Vim, move the cursor horizontally (one character at a time), while j and k move vertically (one line at a a time) to move your cursor. Editing a file is as easy as pressing the i key to enter editing mode. Editing files from the terminal might make you look like a cool hacker or something, but why should we use this text-based program instead of good old Sublime Text?
