How to set a single key binding for a sequence of commands in Emacs

Question

The Emacs manual only has an example to set a binding for a single command. How to do so for a sequence of commands. Specifically the following.

• [M-down] to [C-u 1 C-v]
• [M-up] to [C-u 1 M-v]

Which is practically single line scrolling.

Answer 1

You can use keyboard macros for that task. The link pretty much explains how to do it, for completeness here's what to do:

1. Hit C-x ( to start recording a keyboard macro.
2. Do what the command is supposed to do (i.e. execute commands, hit keys, ...)
3. Hit C-x ) to stop recording the keyboard macro.
4. Execute M-x name-last-kbd-macro to name the last-defined keyboard macro (i.e. the one you just defined).
5. Execute M-x insert-kbd-macro to insert the code of the last defined macro at point, copy it into your init file.
6. Put (global-set-key (kbd "M-n") 'my-macro) into your init file (assuming you named the macro my-macro).
7. Profit!
