Expanded instructions on creating a bookmark
The script includes some rough boundary checking to make sure you're in California, as the state hasn't been magnanimous enough to provide FC maps for OR, NV, AZ or MX.
Be sure to examine the popup closelybefore dismissing it, as it contains the info on which grid you'll need to select, and an '''approximation''' of the location within that grid. The table is presented, rather than the script taking you straight to the assigned grid, to simplify those situations when you may need to access an adjacent map.
Be sure, before lowering any segments, to consult with a senior editor in the area. There are ''occasional'' deviations from the official map, for Waze purposes such as continuity along higher-typed routes.
Feedback will be appreciated. Thanks to SAR85 for inspiring me to finally dig in and learn some javascript, (and fielding plenty of stupid questions from an old dog, about this new trick), and to autenil for coaching about preparing code for bookmarklets.
Copy "Installation" of a bookmarklet is performed by creating a new bookmark, and copy/pasting '''all''' of the code below and make a new bookmark with itinto the URL destination field. Then, simply click that The bookmarklet can then be run by clicking the bookmark with a while your WME page openwindow is centered over the spot where you wish to examine FC.
