How do I copy a named register into the system clipboard without yanking again?

Explanation

If you already have carefully collected text in a named register, re-yanking just to reach the system clipboard is noisy and error-prone. :let @+ = @a copies register a directly into the clipboard register + with no cursor movement and no buffer edits. This is useful in longer editing sessions where register contents are part of your workflow state.

How it works

• @a reads the content of register a
• @+ is the system clipboard register (when clipboard support is available)
• :let @+ = @a assigns one register value to another

:let @+ = @a

Example

Suppose register a contains a multiline SQL fragment you recorded earlier:

SELECT id, name
FROM users
WHERE active = 1;

After running :let @+ = @a, you can paste that exact text into another application with your OS paste shortcut, without touching the current buffer.

Tips

• Use :echo has('clipboard') to confirm clipboard support
• Replace + with * on systems where primary selection is preferred
• For append behavior, assign with concatenation: :let @+ .= @a
