How do I copy the contents of one register to another?

Question

Accepted Answer

`:let @b = @a` The `:let @b = @a` command copies the contents of register `a` into register `b`. This is useful for preserving register content before operations that might overwrite it.

## How it works

- `:let @b = @a` copies register `a` to register `b`
- `:let @+ = @0` copies the yank register to the clipboard
- `:let @a = @a . @b` concatenates two registers

## Example

Preserve your yank before a complex operation:
```vim
:let @z = @0    " Save yank register to z
" ... perform operations that modify registers ...
"zp             " Paste the preserved text
```

## Tips

- `@` syntax accesses registers in Vimscript
- `:let @/ = 'pattern'` sets the search pattern
- `:let @" = @+` copies clipboard to default register
- This works with all register types
- Useful in scripts and complex editing workflows
