[oXygen-user] Oxygen holds cut text for a long time - impressive!

I have several tabs open. One tab contains a text file. I cut some text. Then I did another cut. And a few more. Then I went to the other tabs and did a bunch of work on the data in them - cutting, pasting, moving things around. I did this for a couple hours. Then I went back to the first tab. I was curious to see if the cut text was still hanging around, so I did Ctrl-Z. Wow! The last cut text reappeared. I did another Ctrl-Z and the second-to-last cut text reappeared. Another Ctrl-Z and the third-to-last cut text reappeared. That is impressive! Great work Oxygen team. /Roger
