Disable key input

Disable specific key inputs (keyboard shortcuts) so they can be entered into a page. ## Example use case - You want to use `Ctrl` + `W` in a shell provided by a web page - Example of a shell provided by a web page - [AWS Systems Manager Session Manager](https://aws.amazon.com/jp/blogs/news/new-session-manager/) - `Ctrl` + `W` - Chrome: close the tab (normally takes priority) - shell: delete a word at a time ## How it works 1. Open the current tab in a new Chrome extension popup - This allows Chrome keyboard shortcuts to be intercepted 1. Cancel the event when a keyboard shortcut you want to disable is pressed
