The document list in the sidebar provides an overview of open documents that is often much clearer than the tab bar. I often find it much easier to go to a certain document by looking at the document list. However, currently I need the mouse to actually open it from the document list.

It would be very useful to be able to navigate the document list with the keyboard.

I would propose to add 2 keybinding: One to go to the next document in the document list and one to go to the previous document. When going past the last document in a directory it should go to the next directory in the list and vice versa. When going past the end of the list it should wrap to the beginning and vice versa.

The kate editor has these keybindings under the name "Next Document" and "Previous Document" under "katefiletree".
