For this to happen there needs to be many lines of just spaces and a newline. I talked about in a previous message having 67 of those lines, but I believe on my linux box it required more (less than 100 though). You also need to go to the very end of the file M->, then scroll up through the lines up to the top. I did not make that clear. Here is another take on the recipe, hopefully I can clear up any confusion. This is without resizing the window, so window-body-width should be 80. 1. .\emacs-25.0.93.exe -Q 2. C-x b test-2 3. 4. C-u 80 5. C-j 6. 7. C-u 120 8. You should now be at the bottom of the buffer and at the first column, but it doesn't hurt to hit M-> and C-a, so do that. 9. Now try moving up to the top of the buffer with C-p I experience lag doing this, to be clear about what I mean by that. I can cancel by using C-g, but unless I do that, I cannot execute commands until emacs finishes moving up lines. Which takes much longer than if instead of all spaces, I had instead one period before the newline. I cannot remember if I tested with with emacs -Q -nw on linux. I will report on this tomorrow as well as test the windows build on a newly deployed computer and maybe test it in a virtual box VM. I may also try setting it up tonight if I have the energy.
