This topic was opened here: Shortcut for previous/next note
But was closed without properly being addressed.
There should be keyboard shortcuts to go to the next note and the previous note. e.g.:
Next note: Ctrl + tab
Previous note: Ctrl + shift + tab
Note that when I say "previous note", I do not mean the last note that was viewed (as can currently be accessed using the "back" functionality), but instead am referring to the order of notes in the vertical list of notes for each notebook:
And similarly, "next note" refers to the order of notes in that list.
Joplin seems like a great program, but is still missing some basic features such as this one.
