In the status bar, a right-click brings up a two-item context menu:
Select All and
Copy. I have always found this a little confusing.
Copy implies that it will copy the contents (usually the UNL), but actually you have to select it first before
Copy will do anything. It's possible to select by dragging the mouse, or by using the
Select All menu item.
With the old style UNLs, there was some value in being able to drag-select only part of the UNL, but with the new-style UNLs I don't see the value. it's all or nothing, it seems to me. How about changing the Copy item to Copy All, and let it copy the UNL without the need to select anything? <CTRL-C> could be kept for copying a drag-selected portion.
If it is decided to keep the items the way they are, it would be helpful for the Copy item to be disabled when nothing has been selected. I don't know how tricky that would be from a Qt programming point of view.
