# Virtual Keyboard Alt-Keys Popup Demo

#### Note: Look at this demo source or refer to the documentation on how to set up this extension.

- NOTE In keyboard core v1.28.2, this extension has switched to using `event.key` which is only supported in modern browsers. Use an extension version prior to v2.0.0 (not the core version) to support older browsers.
- Click or press and hold any of the following keys to see a popup:
  - Extension defaults: `1234567890acdeghijklnorstuwyz'ACDEGHIJKLNORSTUWYZ!$()"?`
  - Demo extras: `[`, `]`, `enter`, `☺` & `✙` (examine the source code of this page to see how these were added).
- The keys within the popup are completely customizable. In fact they can include any action key (click or press and hold the enter key).
- In v1.25.11, it is possible to use the physical keyboard. Press & hold an assigned key for the popup to open, then:
  - Use left arrow (`←`), right arrow (`→`), `Home`, `End` to navigate.
  - Press `Enter` to insert the highlighted key.
  - Press escape (`Esc`) to close the popup.
