I thought that was bookmarking in an ebook you are reading rather than bookmarking a web site in the browser because I already have a keymap for that but I will check it out.
I actually read in a review of the 360+ that there was no way to create a BROWSER url bookmark. Glad to find out it is possible after all.
Who would ever design a browser on a device with no way to create bookmarks for web sites???

Thanks.
