When I evaluate something, eg with C-x C-e, the result appears in the minibuffer. Is there a way I can copy it from there? It would be nice to paste it into e-mails etc, but when I press a key it disappears.
From the description of C-x C-e:
"...Interactively, with prefix argument, print output into current buffer."
So, C-u C-x C-e will print the output of the evaluated expression in the current buffer.
See also, (info "(emacs)Lisp Eval"):
"If `C-x C-e', or `M-:' is given a numeric argument, it inserts the value into the current buffer at point, rather than displaying it in the echo area. The argument's value does not matter."
