How to close the window, saving the content of opened page. // I use Esc wq: but it keep open the window

 ESC + :wq

Deleting selected content

how do you select content in VI ? to delete a line, press dd. To delete 2 lines, press 2dd... so on and so forth

going to direct line // Esq /. any other way

ESC + :120

above combination will take you to line no. 120. OR run below command:

vi +120 file_name

Opening new file in same window without closing older one

ESC + :split new_file_name

sorry for the formatting of this post.
