mark linenumbers on gutter by mouseclick and scrollto goto marked lines

[ldijkman]

hello

do not now if this message is shown => my account is flagged by github

is there a demo
of marking line numbers by mousecllick
and scrolltoline gotoline with maybe an up down arrow on the marked lines

 ace.edit("editor").scrollToLine(60, true, true,);
     ace.edit("editor").gotoLine(60, 0, true);

think it would be handy if you jump edit in the document
like i do many times
