An easy way to to get to a line (whose number we know) faster is to combine some existing methods:
:123<CR> or 123G or 123gg
The solution is to map in normal mode the enter to G.
:nmap <CR> G
We can type the line number and then press Enter to get there.
takes you to line 123 in the file,
takes you 123 lines down from your present position.
