Then you repeat (once) with C-x e or (many times) with C-u 1000 C-x e. But it really depends on identifying a search string that will not lead you astray. Also make sure you save a backup of your file before you start - you may have to do this a couple of times before you get it right. Assuming that the simple search above is sufficient, doing C-x ( C-s < 2 0 1 RET 6*C-f ESC 3 6 1 C-x ) to define the macro should be enough. kmacro-edit-macro then shows me this: --8<---------------cut here---------------start------------->8--- ;; Keyboard Macro Editor.
