Ok, here is my final key bar layout. I think (many of) you'll agree that these are very useful keys to have on the key bar for the N900.



And just to collect the codes in one place:

CR = KP_Enter (for hitting enter when the keyboard isn't out)
| = bar
~ = asciitilde
> = greater
` = grave dead_grave (that's my creepy favorite! Note: needs to be hit twice for backquote)
