Navigation is a vital part of text editing. To be very productive, you should be aware of all possible navigation shortcuts in your editor. In this article, let us review the following 8 Vi / Vim navigation options.
  1. Line navigation

1. Vim Line Navigation

Following are the four navigation that can be done line by line.
  • k – navigate upwards
  • j – navigate downwards
  • l – navigate right side

By using the repeat factor in VIM we can do this operation for N times. For example, when you want to
go down by 10 lines, then type “10j”.

Within a line if you want to navigate to different position, you have 4 other options.
  • 0 – go to the starting of the current line.
  • ^ – go to the first non blank character of the line.
  • $ – go to the end of the current line.
