Hit ENTER. You can also use the abbreviated command:
To hide line numbers, type:
Vim line wrap

To remove line wrap, type:
Vim line count
To determine the line count, go to the end of the file by pressing <SHIFT>+g.
Then press <CTRL>+g. A status line will display at the bottom of the editor window indicating the name of the file and what line you're. Since you're at the end of the file, your current line number is the total number of lines in the file.
Vim line length
To determine the length of a line, go to the end of the line by pressing <SHIFT>+4.
Then press <CTRL>+g. A status line will display at the bottom of the editor window indicating the name of the file, what line you're on and also what column you're on. The column indicates the column index of the last character of your current line. Thus, this is the length of your line.

The Vim modeline allows you to customize Vim settings for that specific file. If you're programming in the C language, add this to the bottom of your source code:
Vim will now turn on the autoindent setting. Any Vim setting can be set as needed in this manner.
