CopyslateClipboard history on a Mac: the Windows+V equivalent
On Windows, ⊞V opens a list of everything you copied recently. On a Mac there is no such key. The system clipboard holds exactly one item: copy something new and the previous one is gone. If you copied a link ten minutes ago and then an address, the link is lost unless you go back and copy it again.
What macOS does have
Universal Clipboard lets you copy on one Apple device and paste on another, but it is still a single item. The Finder's "Show Clipboard" in the Edit menu shows the current item and nothing more. Some apps keep their own undo history, which is not the same thing. There is no built-in way to see copied items from earlier.
What a clipboard manager adds
A clipboard manager records each thing you copy, text, links, images and files, and lets you paste any of them later. The useful ones are searchable, so you type a word you remember and get the item back, and they let you pin the things you paste every day so they never fall off the list.
Clipboard history with Copyslate
Copyslate lives in the menu bar. Press ⌥V and a panel opens where you are, listing what you copied, newest first. Type to search, press Return to copy the item back to the clipboard, then ⌘V where you need it. Press ⌘P on anything you use often to pin it; pins keep their own place at the bottom of the panel and are never cleared.
Items from password managers are skipped, because those apps mark their clipboard contents as concealed. You can pause saving from the menu bar icon, or tell Copyslate never to save from a particular app. Everything stays on your Mac; nothing is uploaded and there is no account. Clipboard history is free.
Questions
Does the Mac have a Windows+V key?
No. macOS keeps only the current clipboard item. A clipboard manager such as Copyslate adds a history you open with a shortcut, ⌥V in Copyslate's case.
Is a clipboard history safe to use?
It depends on where it is stored. Copyslate stores history on your Mac only, skips items that password managers mark as concealed, and lets you pause or exclude apps.
How far back does clipboard history go?
As far as you set. Copyslate keeps the number of items you choose in Settings and removes older ones as new ones arrive; pinned items stay.
