Sure. Unfortunately, I can't post a screenshot. I'm not rooted, so I have to rely on the Home + power button combination on my LG G2x for screenshots, and as soon as I hit the Home button, Boat Browser cancels the highlighting operation, so so the screenshot contains just a plain vanilla web page.
How it works, though, is that the main menu has a "copy" command. When you select it, tapping or dragging on the screen highlights a section of the text; when you lift your finger, "handles" appear at either end of the highlighted region to let you adjust the beginning and ending points. That's just like Gingerbread. What's nicer is that, while you're dragging initially or moving the handles, you get a little magnifier window that enlarges the area around the end of the highlighting, making it very easy to control precisely what is selected. Also, there's a popup menu that appears next to the highlighting with the choices "Copy", "Search", "Share", and "Cancel." "Copy" puts the highlighted text in the clipboard; "Search" runs a Google search on the highlighted text; "Share" copies the text into the clipboard and then pops up the usual sharing options, so that the highlighted text gets inserted into the selected app. It's really convenient.
