How does one get top and bottom bar on Adobe Reader app with recent documents button etc.? Adobe Reader has top and bottom bars which shows home/recent, navigation document buttons, navigation bar other "widgets". It looks like this:



The problem is that I do not know how to open it: menu buttons shows useless settings and info button bar. I tried various gestures - it showed only menu or selected the text. However after random swiping, clicking bar popped out. What is the gesture that should open bar?
I am using ICS - Android 4.0.3 on LG phone without hardware search button. Any ideas?
Just tap the document you're reading. (Note, not a long-tap; that opens a different menu.)
From page 5 of &quot;Getting Started with Adobe Reader.pdf&quot; (which downloads with the app):

My PDF documents are in Adobe Reader. Now what do I do?
Tap the middle of the screen once to reveal the toolbars. After a few moments, they disappear until you tap again.
