jqGrid navigator - how to specyfy settings globally? -

i'm using navigator jqgrid , i'm repeating on , on settings such as:

savekey: [true, 13], closeonescape: true, closeafteradd: true 

how can define these settings globally grids on current page?

i know how specyfiy jqgrid settings globally, have problems navigator. sample navigator definition looks this:

    $("#dictionaryelementsgrid").navgrid(         "#dictionaryelementspager",         {             search: false,             edit: true,             add: true,             del: true         },         {             // edit options:             savekey: [true, 13],             closeonescape: true,             closeafteredit: true         },         {             // create options:             savekey: [true, 13],             closeonescape: true,             closeafteradd: true         }     ); 

the object jquery.jgrid.edit responsible default setting of add , edit forms, can include in common javascript code following:

jquery.extend(jquery.jgrid.edit, {     savekey: [true, 13],     closeonescape: true,     closeafteredit: true,     closeafteradd: true,     recreateform: true }); 

the recreateform:true option option recommend use if use events in edit or add form.

another settings jquery.jgrid.nav, jquery.jgrid.del, jquery.jgrid.view , of course jquery.jgrid.defaults can helpful , can used in same way jquery.jgrid.edit above. example,

jquery.extend(jquery.jgrid.nav, {search: false}); 

the settings edit:true, add:true, del:true default (see the source code of navgrid)
