Copy Multiple Code Blocks at Once on Mac

Copy Multiple Code Blocks at Once on Mac

The macOS clipboard holds exactly one thing. Copy a second code block and the first is gone. For anyone moving snippets between files, that limit turns into a tedious copy-paste-copy-paste shuffle: jump to the source, copy, jump to the target, paste, jump back, copy again. You lose your place every time.

There is a better workflow. You can copy several code blocks in a row, then paste them in order without returning to the source between each one. Here is how it works on macOS and how to set it up.

Why the single-slot clipboard hurts in code

Code moves in clusters. You rarely need just one line. You need an import, a function, and its test. You need three config values from one file dropped into another. You need to pull four query fragments together into one statement.

With a single clipboard slot, each of those items costs a full round trip. With a clipboard history, every copy is remembered, so you can gather first and paste later. The mental cost of "did I lose the thing I copied earlier?" disappears.

Two ways to copy many blocks at once

There are two distinct workflows, and they suit different tasks.

Clipboard history: copy freely, paste any item

A clipboard history records each copy automatically. ClipHistory keeps your 150 most recent unpinned clips, plus unlimited pinned clips. You copy code block after code block as you browse a file, then open the history with Cmd+Shift+V and pick whichever block you need, in any order.

This is ideal when you are collecting candidates and are not yet sure which ones you will use or in what sequence.

Paste stack: queue blocks, paste them in order

A paste stack is a first-in, first-out queue. You add several blocks to the stack, then paste them one after another, each paste advancing to the next item. This is built for transferring a known set of blocks in a known order.

The classic example: you have three functions in file A that need to move to file B in the same order. Add all three to the paste stack while reading file A, switch to file B, and paste three times. No switching back and forth.

A concrete workflow

Say you are refactoring and need to move four code blocks from an old module into a new one.

  1. Open the old module.
  2. Copy the first block. Copy the second. Copy the third. Copy the fourth. Every copy is captured in ClipHistory; nothing is overwritten.
  3. Switch to the new module.
  4. Open the paste stack and paste the blocks in the order you queued them, or open the history with Cmd+Shift+V and pick each block explicitly.

Four copies, four pastes, one context switch. Compare that to eight context switches with the system clipboard.

Keep formatting intact

Code is whitespace-sensitive, and pasting through some apps can mangle indentation or inject smart quotes. ClipHistory preserves the text you copied. If a block does pick up stray formatting from its source, the clean AI transform strips it back to plain text before you paste, using your own API key from one of five providers (Anthropic, OpenAI, DeepSeek, Google, or a custom endpoint).

Pin the blocks you reuse constantly

Some snippets are not one-off transfers. A license header, a standard logger setup, or a common error-handling block gets reused across projects. Pin those. Pinned clips are unlimited and never expire out of your 150-clip recent window, so your go-to blocks are always available no matter how much else you copy.

Organize pinned blocks onto boards by language or project so a large collection stays easy to scan.

Everything stays on your Mac

Code often contains things you do not want leaving your machine: internal endpoints, table names, configuration shapes. ClipHistory stores all clips locally. There is no cloud, no account, and no sync server. The blocks you copy stay on the Mac where you copied them.

The app is signed and notarized by Apple, ships as a universal binary for Apple Silicon and Intel, and runs on macOS 12 and later.

Summary

The single-slot system clipboard makes multi-block copying painful. A clipboard history lets you copy many code blocks freely and paste any of them later; a paste stack lets you queue a known set and paste them in order. Together they cut the context switching that makes moving code around so tedious.

Tired of the copy-paste shuffle? Get ClipHistory for macOS ($19.99, one-time) and start collecting code blocks before you paste them.
