DeepLKey: DeepL Keyboard Shortcut

Description

DeepL's desktop apps (e.g. DeepL for Mac) are very useful, especially sending selected text by keyboard shortcut (pressing `Command-c` twice). But unfortunately, they don't provide any way to customize appearance like font size, etc. It's a bit hard for me to use it for long time with such a small text. This Chrome extension provides a keyboard shortcut (default `Command-b`) to send selected text to DeepL translator web page. It's just a web page so that you can change font size by changing web browser settings.

## Usage

- Select text by mouse or keyboard
- Press `Command-b` (macOS) or `Control-b` (other OS)
- Or right click to open context menu and choose `DeepL Translate`

## Settings

### Change keyboard shortcuts

- Open extensions setting page `chrome://extensions`
- Open menu by clicking `hamburger button` (triple bar icon) on the left of `Extensions`
- Click `Keyboard shortcuts`
- Click the pencil icon on the right of `Open DeepL`
- Input key stroke. Default is `Command-b` (macOS) or `Control-b` (other OS).

### Change settings by popup dialog

You can change translation language, color theme and window position by Chrome's popup dialog.

- Click the DeepLKey icon (you can "pin" the icon)
- Change settings by selections and buttons. See YouTube video http://www.youtube.com/watch?v=gZVzj4uDTss for more details.

## Limitations

- In certain pages (e.g. Kaggle Notebooks), keyboard shortcut cannot get selected text because `window.getSelection()` returns empty. In that case, try context menu instead.
- When you use context menu, Chrome removes newlines from selected text because `info.selectionText` removes newlines. See https://bugs.chromium.org/p/chromium/issues/detail?id=116429

## TODO

- Find a way to get selected text in case `window.getSelection()` returns empty.
- Sophisticated UI for translation.html
