**List of steps to reproduce** (step by step, including full links if applicable): * Edit a page in VisualEditor * Open an existing template for editing * Type something in some template data field * Press Ctrl+backspace **What happens?**: The field is removed (same as if you clicked on the little trash icon above it) **What should have happened instead?**: The last word in the textarea is deleted **Software version (if not a Wikimedia wiki), browser information, screenshots, other information, etc.**: Chrome 98 on Ubuntu 20.04. The specific article and template where I encountered this is https://wikitech.wikimedia.org/wiki/Deployments -> edit "Wednesday, February 16" section -> "21:00–22:00 UTC, UTC late backport window" template -> "Changes" field.

Acceptance criteria: [] Make Ctrl+Backspace work only on Mac, not on PC. [] Change the keyboard event handler so it doesn't do anything when the shortcut was pressed with the focus being in an `<input>` or `<textarea>`. [] For consistency, change the Ctrl+Shift+Up/Down shortcuts the same way. [] Make sure all 4 Ctrl+Shift+Left/Right/Up/Down can be used in text fields without triggering unexpected behavior. * No update to the help page needed.
