I’d like to have a hotkey that copies the filename of the note I’m currently working on.
Often when I type in one note, I want to make a link to that note in another panel. So I grab the mouse, select the text in the header of the current file (the filename), select it, do Ctrl-C, and move to the other note and paste it there.
It would be a much smoother operation for me if I can simply copy the filename of the current note. 
Normally, if you link your notes, Obsidian will try to guess what you’re trying to do. However, if your filename is quite complex, you might have trouble. So I guess this should be added.
I’d love to be able to drag one note into another and have it appear as a link.
This would be a huge benefit!
This request can be closed. Since I made the request Obsidian added the ‘Copy file path’ hotkey, which copies the current note’s filename. 
(Thanks!)
