If you just went to one other line, eg, line 150,
''
will get you back to line 100. If you searched and got to line 150,
then hit 'n' and got to line 163, then another 'n' brought you to line
213, "''" would then take you back to line 163.
If you want to literally mark line 100 as your "anchor", which is what I
think you actually want, then
mm
will mark that as mark 'm'. I just use 'm' because it's the same key,
and 'n' as a secondary mark, but others might use marks 'a' and 'b'
("ma" and "mb" commands). In that case
'm
will bring you back to the beginning of line 100 no matter where you
are. Haven't used this in a while (farther to reach the key :D ), but
`m
should bring you back to the exact character on line 100 should you
desire.
