Alternate datasource/toggle pane with keyboard

I looked at online help and made a search here for "data source shortcut" and I found nothing about a shortcut to the navigation pane's datasource menu drop-down. I want to be able to exchange datasources with keyboard. When I try to navigate to that field with tab/shift-tab after using the shortcut for the filter list, it doesn't look like the selection is going anywhere and after some typing I'm back to the filter field. I'm using Remote Desktop Manager Enterprise v9.2.10.0.

I would like to have a shortcut to toggle the navigation pane too. Should I make a feature request? Is there anyway to do what I want using the current version?

Thank you.

edit: just found the shortcut to toggle the navigation pane: alt+f8.
