How can I copy a line 10 times easily in Emacs? I can't find a copy-line shortcut or function. I can use C-aC-spcC-eM-w to laboriously copy the line but how can I then paste it more than once?
Any ideas before I go and write my own functions.
Copying:
If you frequently work with lines, you might want to make copy (kill-ring-save) and cut (kill-region) work on lines when no region is selected:
(defadvice kill-ring-save (before slickcopy activate compile)
"When called interactively with no active region, copy a single line instead."
(interactive
(if mark-active (list (region-beginning) (region-end))
(list (line-beginning-position)
(line-beginning-position 2)))))
(defadvice kill-region (before slickcut activate compile)
"When called interactively with no active region, kill a single line instead."
(interactive
(if mark-active (list (region-beginning) (region-end))
(list (line-beginning-position)
(line-beginning-position 2)))))
Then you can copy the line with just M-w.
Pasting:
Often a prefix argument just performs an action multiple times, so you'd expect C-u 10 C-y to work, but in this case C-y uses its argument to mean which element of the kill-ring to "yank" (paste). The only solution I can think of is what kronoz says: record a macro with C-x ( C-y C-x ) and then let the argument of C-u go to kmacro-end-and-call-macro instead (that's C-u 9 C-x e or even just C-9 C-x e or M-9 C-x e).
Another way:
You can also just stay in M-x viper-mode and use yy10p :)
