This is a Pragtical plugin for opening links. Should work on Lite-XL too, but I think you may have to remove the contextmenu code.
Navigate to the plugins folder (usually ~/.config/pragtical/plugins) and run the following command:
git clone https://github.com/irisdominguez/pragtical_link-opener_plugin link_opener
Alternatively the init.lua file can be renamed link_opener.lua and dropped in the plugins folder.
Move the cursor to any link, and press Ctrl + Enter while on the link.
Alternatively, right click on any link and select Open link from the context menu, or Ctrl + Alt + Left click on any link.
Pull requests are welcome. For major changes, please open an issue first to discuss what you would like to change.
