Keyboard & clipboard ​

Try it ​

A text editor with the clipboard made visible. Select something in the top window and copy it — it appears in the Clipboard window below, because in JSVision the clipboard is an editor. Select inside that window and paste, and you get exactly what you selected there.

A cut-down text editor beside the shared clipboard, shown live as you cut, copy, and paste.

The default chords ​

Every editable widget — Input, Editor, Memo, ComboBox, History, and anything built on them — supports selection and clipboard out of the box, with no per-widget wiring:

  • Ctrl+A select all · Ctrl+C copy · Ctrl+X cut · Ctrl+V paste
  • The classic DOS aliases Ctrl+Ins (copy) / Shift+Ins (paste) / Shift+Del (cut) work too.
  • Shift+arrows or a mouse drag extend a selection.

Copy and cut fill a shared in-app buffer, so text copied in one field pastes into another — or between an Input and an Editor. When the terminal supports it, they also write the OS clipboard (OSC-52). Paste works on every terminal via the in-app buffer; no clipboard read is performed.

The application shell installs this by default. Choose which chord sets are bound with clipboardKeys on createApplication (or createEventLoop):

ts
import { createApplication } from '@jsvision/ui';

// 'both' (default) = modern Ctrl+A/C/X/V + the classic Ins/Del aliases.
// Use 'modern', 'classic', or 'none' to free keys for your own bindings — e.g. an
// editor that needs Ctrl-letter chords sets clipboardKeys: 'none'.
const app = createApplication({ clipboardKeys: 'both' });

A user-supplied keymap always wins over these defaults on a conflict. To grey a Cut/Copy menu or status item when nothing is selected, bind the reactive Input.hasSelection signal.
