Buffer Feature Suggestion

[chadack]

I think it would be enormously helpful for keeping track of important information if there was some way to permanently highlight text in the buffer.

For example: In the current arrangement when you put the cursor at a location and then hold down the left mouse button while you move through a line of text it becomes highlighted. But as soon as you do that operation again the original highlighted text stops being highlighted.

I would like to see the ability to highlight text and keep it highlighted. For example perhaps one could hold down both left and right mouse buttons together to make the text highlighting permanent.

Does anyone else think this would be useful?
