customize shortcuts: remove 'hash pointer' and have only 'go to line' on CTRL+L

Question

Hi all In aptana Studio 3 I don't find useful CTRL+L -> 1 for 'hash pointer' and CTRL+L -> 2 for 'go to line' and I would like to get rid of the first one and easily go to line with CTRL+L and that's it. Anybody knows how to do it? - Thanks
