LL has changed the way the home page for the F1 browser works, so here’s an updated version of how to change it on Windows machines for those who liked the no longer functional old hack.
There’s a file C:\Program Files\SecondLife\skins\xui\en-us\floater_html_help.xml with a line that reads:
The “http://secondlife.com/app/help/” can be replaced with something else, like Google, as shown below:
LSLwiki.com is a likely choice for scripters.
Or create your own web page with links to the sites of your choice.
This should be done while SL is not running.
The start_url is the home location, so the first time you use this you need to press home to make the browser go the url you provide.
