good question i have no looked at this in so long, I'm not sure. Sorry I'm no help. I imaging you could extend this and use something like lodash debounce to detect a second set of shortcut keys after the first one has been met

Thank for quick response, i see that in combination with mousetrap it is possible, so i only add a global ALT+ for all shortcuts here and get the result that i want!

// ... before
bindKeyToRoute: function (key, route) {
    Mousetrap.bind([key], function(e) {

// ... after (for have `ALT + key` combination)
bindKeyToRoute: function (key, route) {
    Mousetrap.bind(['alt+'+key], function(e) {
// ...

Same thing work also if we define directly in keypressAction() cause it pass key like a string

// without modifing script, pass `ALT + key` directly for keypressAction binding
$(document).keypressAction({
    actions: [{
        key: 'alt+b', 
        route: "...my/url..."
    }]
});

That's it! Thank you for sharing. Just a note, if your binding html elements you can use the accesskey attribute for buttons and inputs I think.
