Here's a bunch of things to try to get started. If you have problems, say which ones worked for you and which didn't.
Type date somewhere and middle-click on it. A new +Errors window should pop up with the current date. Middle-click on date again. The date should appear a second time in the +Errors window. Now type "echo hello world" somewhere (without the quotes). Highlight it using the left button and middle click on the highlighted text. "hello world" should appear in the +Errors window. Left-click on the echo hello world so that the highlight goes away. Then highlight "echo hello world" using the middle button. A second "hello world" should appear in the +Errors window. In the +Errors window, right click on one of the "hello"s. The mouse pointer should jump to the other hello, which should be highlighted. Leave one of the "hello" highlighted in the body and middle click the world "Look" in the tag (the blue line). Each time you middle click "Look" the highlight should jump to the other hello, just like it was when right clicking directly on hello. But the pointer will not move. In the tag of the +Errors window (the blue line above it), the word Look is at the end of the tag. Put the cursor after the Look and type "hello", so that the tag end reads "Look hello". Highlight "Look hello" using the left button and then middle-click the highlighted "Look hello". Each time you middle-click the highlighted "Look hello", the highlight in the body of the window should move to the other "hello". Left-click in the tag so that the highlight on "Look hello" goes away. Now use the middle button to highlight "Look hello". The other "hello" in the body should be highlighted and the mouse pointer should jump to the now-highlighted text. Russ
