Custom forward and backward buttons

Hi, I'm creating content that uses a custom Skin and not the Articulate player.

Some of the content is 100 slides or more, so putting code on all the buttons to jump to the right slide is a lot of work.

The Jump to "Next Slide" and Jump to "Previous Slide" triggers do not work, because I have a menu that lets you revisit topics, and if I use these them when on slide 50 if I Jump by the menu to Slide 10, when I useJump to "Previous Slide", articulate will go from Slide 10 to 50 and not Slide 9.

How can I make this? Is there a JavaScript Solution to always move up and down to the correct slide.

Thanks
