No, I think that exits. C-c k kills the buffer, C-x 0 (zero) will kill the frame. But I may have changed my binds and can never remember which is window and which is frame in emacs terms.
However, it’s somewhat moot as just about everywhere you run emacs, it’ll open up in gui mode and you can use the file menu. (Or use F10 to bring up the menus in terminal, but I have no idea where on the manual it would say that)
The Dash Berlin ASOT 600 set (specifically Sofia) got me through my dissertation writing. Even now, if I sit down with a coffee and turn on the set, within the couple minutes I am completely in the zone for working. It’s like a brain hack for me.
I also like the Music for programming site (specifically RITES) which is also good for some focus music.
I’ve tried to get some folks to post their dissertation writing music and form a massive playlist, as it seems really common to have some certain song or album. I’m sure it’s similar for other intense work flows too.
