I would like to make a very basic macro on my Mac, to have a command that writes a list of slashes in the current file : ////////////////////
The "Basic emacs macros" section of the manual says :
‘<F3>’ Start defining a keyboard macro (‘kmacro-start-macro-or-insert-counter’). ‘<F4>’ If a keyboard macro is being defined, end the definition; otherwise, execute the most recent keyboard macro (‘kmacro-end-or-call-macro’).
Unfortunately, on my High Sierra Mac the F3 and F4 keys have a builtin "Mission Control" behaviour, so I cannot define macros this way.
How to fix this ?
