Here I have collected some script I've written for everyones favourite editor, emacs.
switch-buffer.el - makes it possible to mark buffers with C-M-<0-9> so it's easy to switch to that buffer with M-<0-9>. Also supports automarking buffer when opening a file. [v0.1.4]
bookmarks.el - gives you the possibility to bookmark a position in a specific buffer with s-<0-9> and later jump to that position from any buffer with C-<0-9>. [v0.1]
