Roblox on PC can’t directly access your system clipboard for security reasons, so there isn’t a real “clipboard access” feature you can enable in-game. The closest workaround is to use a TextBox, focus it, and have the player copy the selected text with Ctrl+C.

What works

  • Put the text in a TextBox.
  • Make it non-editable if you only want it copied.
  • Auto-select the text with CaptureFocus(), SelectionStart, and CursorPosition.
  • Tell the player to press Ctrl+C to copy it.

Example workaround

A common pattern is:

  • textbox:CaptureFocus()
  • textbox.CursorPosition = string.len(textbox.Text) + 1
  • textbox.SelectionStart = 1

That pre-selects the text so the user only needs to copy it manually.

Important limit

Roblox does not expose the clipboard as a Lua API, and pasted text is basically limited to what the textbox supports; the system clipboard itself is not available to scripts. On Windows, clipboard history is managed by the OS, not by Roblox, so settings like Windows + V apply to Windows generally, not Roblox scripting.

In plain English

If your goal is “make a button copy text automatically,” Roblox PC does not support that directly. The best you can do is show the text in a textbox and make copying as easy as possible for the player.

TL;DR: You can’t access the clipboard directly in Roblox on PC; use a focused, pre-selected TextBox and have the player press Ctrl+C.
