How do I create a macro without recording it?

Explanation

The :let @a = "..." command sets the contents of a register directly. This lets you create macros by typing the keystroke sequence as a string.

How it works

• :let @a = "commands" sets register a
• Special keys use backslash notation: \<Esc>, \<CR>, \<C-a>
• The macro can then be run with @a

Example

Create a macro that comments a line with //:

:let @c = "I// \<Esc>j"

Now @c adds // at the start of the line and moves down.

Tips

• Use \<Esc> for Escape, \<CR> for Enter
• Double-quoted strings interpret backslash sequences
• Single-quoted strings are literal (no interpretation)
• This is useful for sharing macros or putting them in your vimrc
• Combine with :noremap for a more permanent solution
