You could try C-o (open-line by default) or C-z (suspend/minimize by default). I use C-z as a personal command prefix. Emacs really puts those ctrl shortcuts

You could try C-o (open-line by default) or C-z (suspend/minimize by default). I use C-z as a personal command prefix. Emacs really puts those ctrl shortcuts to work, it's damn near impossible to find one that I don't use at least semi-regularly. edit: You could maybe try C-9 or use a symbol. I was only thinking in letters.
