Is there a way to Page Down in Inventory lists?

Scrolling with the mouse wheel is pretty slow and laggy and clicking on the scroll bar jumps to that point in the inventory rather than paging down. Page Down key does not work.

 

I think using the predefined Tabs or the manually search function in your inventory are the only possibilities to manage your inventory.
And in my humble opinion especially the full text search function is very helpful. E.g. just type “ore” into the inventory search field and everything that do not contain “ore” in its item name is hidden.

 

I was thinking that page down would be really helpful for browsing inventories, especially vendors. I use the search function when I know exactly what I want, but browsing an inventory would really be improved with a page down option if there isn't one.
