I accidentally removed the ribbon in my text file. How can I add it back?

skylog

hello,

i was editing a text file in dropbox and trying to eliminate the underlines under some text that may not be proper grammar. i went into the settings and misunderstood the option that said something to the effect of remove the ribbon (or something, i can not quite remember).

what i did was remove the bar above the keyboard that had the settings and several other options. 

now it is gone...and i can not seem to find anyway to get to those settings to put it back.

any ideas would be appreciated.

thanks

EDIT: i figured it out. long press the number button option
