Pressing search button in jqgrid toolbar opens advanced search window. Pressing enter key does not start seach. To start search, search button needs to be clicked.

How to allow enter key press to start search like in clicking in search button ?

To implement search on Enter key one have to implement binding to keydown event to any input fields and force searching on Enter. If you include jQuery UI jquery-ui.min.js then you can use $.ui.keyCode.ENTER instead of 13 for the better readability of the code.

The code can be like

$.extend($.jgrid.search, {
    // ... some other default which you use
    afterRedraw: function (p) {
        var $form = $(this), formId = this.id, // fbox_list
            bindKeydown = function () {
                $form.find("td.data>.input-elm").keydown(function (e) {
                    if (e.which === $.ui.keyCode.ENTER) {
                        $(e.target).change();
                        $("#" + $.jgrid.jqID(formId) + "_search").click();
                    }
                });
            },
            oldOnChange = p.onChange,
            myOnChange = function (param) {
                var $input = $form.find("td.data>.input-elm"), events;
                oldOnChange.call(this, param);
                if ($input.length > 0) {
                    events = $._data($input[0], "events");
                    if (events && !events.keydown) {
                        bindKeydown();
                    }
                }
            };
        p.onChange = myOnChange;
        bindKeydown.call(this);
    }
});

The demo demonstrate the code live.
