First, Happy New Year
gg/Shift+Right - I’m afraid you’re mixing different concepts here.
Shift+Right - focus this list item. It does not work on the Due page, though it could, but this not implemented yet.
gg has the semantics “go to this link”. If you use this shortcut on an item with a link inside - this link is opened. If this link is local, it is opened in the same tab. If this link is external - it is opened in the new tab.
If the current selection is on the Due page - there is a link on the right part of this page with title “Go to the list context” - and this is basically it, you can navigate to the list item in the list context, and if this list item has sub-items, Checkvist also activates focus on the list item. By default, the navigation is done without opening a new tab (because the link is local, i.e. does not lead to the external site), but you can change the behaviour if you press “Shift” before pressing
gg. The link will also be opened in the new tab if you enable option
Open links to list items in a new tab in
gg is about clicking links from keyboard, not about focusing nodes. You can always open link in new tab keeping “Shift” key pressed, otherwise, the behavour is defined depending if the link is internal or external. I’m afraid we are not going to change this semantics in the future.
All the best,
