"Toggle Link" Button

Hm, this sounds like you’re trying to use it exactly as intended: Ctrl+Click opens the URL for me just fine on Linux. I’ll try to see if I can reproduce the issue on Windows. The URL is passed on to the system, so it should open fine as long as the URI scheme is registered properly – did you enter URLs without a protocol (i.e., http://)? That could cause the system not to be able to do anything with the link. (It’s worth considering to default to http:// if the URL has no protocol as well.)
