Explain the problem as you see it
It would be very helpful to navigate between nodes using only the keyboard. Just like Today node can be opened with Ctrl+Shift+D.
Why is this a problem for you?
This would make navigation much more comfortable between frequently used nodes, like tasks and daily journal. Especially when proper mouse is not available.
Suggest a solution
For this, all we need is the ability to assign shortcut keys to "search and open node" action.
This is straightforward to implement in the UI. In the search view, we need the ability to record a shortcut via Ctrl+Shift+K, like in the command view.
