2. Type your keystrokes.

To run the keystrokes you've just recorded, use one of:

• Alt+x call-last-kbd-macro
• Alt+x kmacro-end-and-call-macro 【Ctrl+x e】

another useful command to run key macro is

• Alt+x apply-macro-to-region-lines

Save Keyboard Macro

Key macro can be saved for future use.

To save the macro:

1. Alt+x name-last-kbd-macro and give it a name.
2. Alt+x insert-kbd-macro. This will insert the lisp code for a named kmacro at the cursor position.
3. Copy and Paste the code into your Emacs Init File.
4. In future emacs session, you can call your kmacro by name. e.g. Alt+x name.

You can now also give it a keyboard shortcut, such as F8. [see Emacs: How to Define Keybinding]
