Fast switching between two lines in file in vim

Question

sometimes I have to switch between 2 lines. To do this, I have to pass line number. Are there shortcuts to moving between 2 last 'visited' list. Something similar to '. (it moves to last edited line)

Answer 1

The command has two forms:

``

or
