Adding a button next to bulk actions

Hi,
In the backend I have customized the table for one of my post types (custom_columns, sortable, meta_filter_posts etc.) and I’d like to add a button next to bulk action and filtering.

In other words I want to add another div in .tablenav div.
<div class="alignleft actions"><!-- My Code --></div>

EDIT: Made a screenshot to be clear what I mean ??

Any idea what action hook to use to do that?

Thanks in advance
Hynek
