How to type a backtick!
Switch to the Romaji then hit 123 button then hit #+= button. Next hold down on the apostrophe symbol and when the key pops up, don't pick one, but instead just release the key, and now, a small blue round "menu" appears under the insertion point in the text, which will let you pick a backtick from the cool little pop-up "menu" display under the characters (a UI element not found on the US interface!). It's the farthest option to the left. I haven't verified yet if it's a true unicode backtick tho... Anyone?
