Home screen's menu; the online "Help" for the Nexus 7 (and how to save it to the tablet)
Chuck, if you mean naming folders, click on a folder in the "hotseat" (most people call it the Favorites, but a Google documentation I was reading called it "hotseat"), click where it says "Unnamed Folder,", and type a name. If you mean actually displaying the folder name all the time, i.e. when the folder is collapsed, that may require a third party launcher.
I recently got a
Motorola KZ500 Bluetooth keyboard with integrated trackpad off Woot.com (yeah, a bargain for the price I paid). Connecting to the N7, there are many keys that "just work." It seems this is a Windows keyboard (with dedicated Windows keys) that they've repurposed specifically for their Android phones (e.g. Xoom, Atrix, Razr), and labeled the special keys with Android functions: search, menu, home, back. Media player keys work with Google's Play Music app. Volume up and Volume down work.
The surprise to me is how easy it is to navigate the home screen with arrow keys ... someone at Google really thought out the sequential arrangement of icons, hot seat folders, etc. when you tab or arrow around. Just typing on the home screen brings up a Google Now search ... cool.
And the JB home screen has a menu! Brings up a menu with Wallpaper, Manage Apps (Settings | Apps | All), System Settings, and Help. Help takes you to
www.google.com/mobile/bin/topic.py. The default choices there look pretty dry (even the pages are the usual boring Google branding). Click "Android 4.0" though and you enter a special place, "Android OS Help" with a sub-menu, "Android 4.1." Choices are Xoom, Nexus S, Galaxy Nexus, Nexus 7. Nexus 7 takes you to a mobile version of
this section. If it looks familiar, it appears to be the same chapters and sub-heads as the
Nexus 7 Guidebook. I still recommend getting the book, mark it in Play Books for "Keep on device," and creating a shortcut on the Home screen. (I'd kind of wondered where the Galaxy Nexus "guidebook" was, and now I've found it.
