; Tracks the last 10 things you've copied. Press Ctrl+Alt+V to see a
; numbered list and pick one to copy back to the clipboard.

; (Windows 10/11 already has a built-in clipboard history via Win+V —
; this is a minimal roll-your-own alternative for older systems or
; when the built-in one is disabled by policy.)
