I love the way my droid2 has 'predictive text' and would like to know how to bring it up manually because it goes away in certain situations - i.e. after ending a word and then backspacing to change it, sometimes it will just show ending punctuation suggestions and i can't get it back into word suggestion mode. is there a way to make it come up again manually? i am terribly slow phone typing so the word suggestions save me a lot of time 
also, is there a 'undo' shortcut? i have the ones for cut-copy-paste but haven't seen undo
