Exit note key

simple one - what key do you use to exit a note and save the changes? in evernote it is the escape key to return to the note list - what is the general keyboard layout here? it seems to be very mouse oriented for a note taking program. i noticed for instance that the main menu does not work properly with the left and right arrow keys to move among the menus. i also noticed that if you hide the sidebar, the tab key still goes there and you can arrow up and down and change the notebook being used - seems like it should not. thanks!

CTRL-S to save + sync ; or … nothing as Joplin save all alone

ok so then there is no way to save and exit the note editor back to the list with the keyboard - other than the shortcut for the list? thanks
