Culled these tips / shortcuts from the first reviewers critiques.
1. Because there is NO "power" button, you must hit the Escape key once the Gem is open or you get to the generic Power Off / Reboot via Esc-Spacebar.
2. Because there is NO volume adjustment button / toggle, you must "use function keys (Fn-C and Fn-V) to adjust volume".
3. "Whatever you do, NEW USERS, don't set the pop-up Planet toolbar to always on. What happens is that the toolbar's menu grabs the focus and can't then be dismissed."
4. The workaround when the physical keyboard doesn't work, you can access the on-screen soft keyboard via the Emoji key sequence Fn-? (function key then question mark key).
Please share your tips / shortcuts, etc. herein.
THNX.
