Go to last line

I often use Ctrl+G (Goto Line), enter line number to go directly to the specific line number.
My wish is to be able to go directly to the bottom of the script, without knowing the highest line number in the object or file or source viewed, by either not entering a line number, or hitting "Last line" or similar.

I've just seen that 13.2 is actually doing this, if you enter a very high line number.
Up to 13.1 - enter 20000 in a script that has 5000 lines, and the cursor will jump to line 1.
From 13.2 - enter 20000 in a script that has 5000 lines, and the cursor will jump to line 5000.
Nice - but well hidden - feature.

CTRL+End will take you to the last line.

Thanks.
Thing is, it's not a very nice key combination on a mac.
But the new Ctrl+G 55555 works as a charm - specially when you use Gtrl+G a lot.
