shortcut_params allows you to add additional link parameters when using a TYPO3 shortcut page.
Installation via composer is recommended:
composer require smichaelsen/shortcut-params
Install in the TYPO3 Extension Manager afterwards.
The extension is usable right away without further configuration. When editing a shortcut page, you notice a new form field for your additional attributes.
Please provide "raw" GET parameters - they will be parsed by typolink (and realurl if applicable) afterwards:
?tx_myext_plugin[foo]=bar
Also providing sections is supported:
?tx_myext_plugin[foo]=bar#content
