How to run a macro on all lines in a file or on all selected lines?

You can use the “apply-macro-to-region-lines” function to apply the last defined keyboard macro to all lines in a region. So, the steps you follow are:

1. Define your keyboard macro
2. Select the whole buffer with the mark-whole-buffer command (by default, it’s bound to C-x h). Alternatively, if you just want to change a certain number of lines, just select the lines you want changed.
3. Run the apply-macro-to-region-lines function (by default, it’s bound to C-x C-k r).
