On my N900 I have to swipe left to right very quickly & I mean fast! Then select the large arrow that appears bottom left(a red line goes through it), again I do this quickly as it disappears after ~1s, and then I can select text copy etc.

Repeat manically if large arrow does not appear first time lol This process works better for me if I swipe the bottom 1/5 of the display.

Just found hover mode Moving slowly in from bottom left and moving slighty upwards.
