Button

Modifier Guard Button

A dangerous action guarded by a held key: the button stays locked until Alt is held down, and the label explains what to do.

React + Tailwind, shadcn-compatible: press “Copy for AI” and your Cursor or Claude Code agent installs it with the shadcn CLI.

What you can change

  • the children and lockedLabel labels
  • the guard key through the modifier prop (Alt, Shift or Control)
  • the onConfirm handler: it fires only in the armed state

A link for your AI agent: preview, code and instructions.

FAQ

How do I add Modifier Guard Button with Cursor or Claude Code?
Press “Copy for AI” on this page and paste it into your agent's chat. The instruction contains the shadcn CLI install command, the dependencies and what to keep, so the agent installs this exact component instead of recreating a lookalike.
What does Modifier Guard Button depend on?
No npm packages beyond React and Tailwind CSS.
What can I change in Modifier Guard Button?
Adapt: the children and lockedLabel labels; the guard key through the modifier prop (Alt, Shift or Control); the onConfirm handler: it fires only in the armed state. Keep as installed: reading the modifier flag from the event rather than from event.key: the state then survives a keyboard layout switch; the window blur listener: without it a key released outside the tab leaves the button armed; aria-disabled and cancelling the click while locked — the button stays in the tab order but must not fire.
Is Modifier Guard Button free?
Yes. The preview is open without an account; with a free account you can copy up to 20 components a month.

For developers

Technical notes

The component is self-contained: one file, no dependencies, its own palette in the local --vibeui-button-055-* variables. Client component: the keydown and keyup listeners sit on window and read the modifier flag (altKey, shiftKey or ctrlKey) straight from the event, so the state does not fall out of sync when the layout is switched. The window's blur is listened for as well: a key released outside the tab would otherwise leave the button armed. The armed state is announced through aria-disabled, and a click in the locked state is cancelled.
