Clipboard Accumulation: double-tap ⌘C to append copies into a single pasteable item

[dulangaj]

Double-tapping ⌘C appends subsequent copies to the most recent clipboard item, allowing multiple non-contiguous selections to be pasted at once.

Motivation

Many workflows involve collecting rather than replacing clipboard contents:

• copying multiple quotes from an article or PDF
• assembling code snippets from non-adjacent locations
• aggregating IDs, URLs, or log lines from different screens

Behavior

• A double-tap ⌘C appends the newly copied content to the previous clipboard item
• Accumulated content is stored as a single clipboard entry
• A standard single ⌘C behaves exactly as before
• Order of copied items is preserved
