I like this! But pressing Enter on a note should open the note for editing. That’s a convention I’d like to keep. Stick with F2 for renaming or something else like Shift-Enter. I could see Alt-Enter opening an options menu for the selection, and being able to arrow-up/down to navigate that.
Furthermore, pressing something like Ctrl-Shift-Arrows could move a note around the directory tree. I imagine Obsidian would want to wait until the note was committed to its final spot before fussing with link reassignments though.
