vim-signature is a plugin to place, toggle and display marks.

Apart from the above, you can also

• Navigate forward/backward by position/alphabetical order
• Displaying multiple marks (upto 2, limited by the signs feature)
• Placing custom signs !@#$%^&*() as visual markers

Displays the marks as signs. Also place visual markers

Alphabetical mark traversal and more.

Requires Vim to be compiled with +signs to display marks.

I recommend using a plugin manager to do the grunt work for you.
If for some reason, you do not want to use any of them, then unzip the contents of the .zip file to your ~/.vim directory.

Once that's done, out of the box, the followings mappings are defined

  m[a-zA-Z]    : Toggle mark
  m<Space>     : Delete all marks
  m,           : Place the next available mark
  ]`           : Jump to next mark
  [`           : Jump to prev mark
  ]'           : Jump to start of next line containing a mark
  ['           : Jump to start of prev line containing a mark
  `]           : Jump by alphabetical order to next mark
  `[           : Jump by alphabetical order to prev mark
  ']           : Jump by alphabetical order to start of next line containing a mark
  '[           : Jump by alphabetical order to start of prev line containing a mark

  m[0-9]       : Toggle the corresponding marker !@#$%^&*()
  m<S-[0-9]>   : Remove all markers of the same type
  ]-           : Jump to next line having same marker
  [-           : Jump to prev line having same marker
  m<BackSpace> : Remove all markers

This will allow the use of default behavior of m to set marks and, if the line already contains the mark, it'll be unset. The default behavior of ]', [', ]` and [` is supported and enhanced by wrapping around when beginning or end of file is reached.

The command :SignatureToggle can be used to show/hide the signs. Note that this does not delete any of the marks but only hides them. This is a buffer-specific command.

If for some reason, the marks and their sign displays go out of sync, use :SignatureRefresh to refresh them.
