The numbered marks, are used for trace history of the cursor position in the last closed session vim...and ok. therefore:
0
contain last position of the cursor before close VIM,
1
contain the penultimate position of the cursor before close VIM,
2
third last...ecc.
But why i when view list (with command :marks) outs duplicate lines?
