A while ago I noticed that shift space no longer seemed to scroll backwards in pdf-view-mode (nor any other mode where it would make sense). I could swear it used to work fine, and it even works on my windows machine. However I’ve now tried emacs 28 & 29 (my own config and -q in GNOME, a terminal emulator with --nw and a tty and all seem to have the same issue.

If I try to bind S-SPC to anything, then C-h k still only sees SPC being pressed, so it seems like emacs is just ignoring the shift key being held.

Anyone else had this problem? It’s not the most serious thing in the world, but it is puzzling.

    Shift+SPC is not able to be represented on a TTY, due to the way that input is encoded. It should be possible in X11, but my Emacs also does not seem to register it.

      I’m on wayland with pure GTK, so it seems neither x11 or pgtk work. Bizarre that windows seems to be the only place it works.

        Maybe you can use general.el? That’s how I have it bound in my X11 GUI Emacs on a minimal Linux installation and it registers without issue.

    How exactly did you bind to S-SPC?
    (define-key ... [S-SPC] ...) should not work, but (define-key ... (kbd "S-SPC") ...) should.
    What does C-h l say after you’ve hit S-SPC?

    I think it’s a pgtk thing. Tried compiling without pgtk and it worked just fine.
