web
The web
command is used to open a web page in your default web browser.
Example I
web https://reddit.com
Specifying the protocol is not necessary and the launcher will default to prefixing http://
in that case. Most websites will automatically reroute http traffic to https if it's available so you can safely ignore the protocol.
Example II
web reddit.com
Note
This command will only work if you have a browser installed on your device which handles requests to open URLs. Ofcourse, how will it work without a "web" browser?
