IntelliJ always seems to do The Right Thing. It comes with code-aware features such as Smart Line Joins, and Smart Line Split. However, there is not Smart Copy to complement Smart Paste. Besides symmetry, there are good reasons to have Smart Copy. Supppose, you have a SQL query in Java Code and you want to run it in SQLPlus to see an execution plan. Another example could be embedded XML as compile time constant. When you copy a query embedded in a Java class, perhaps you are interested in its value without without the quotes and plus characters clinging to the copied text.
If you are a surprised user, you are not alone. Smart Copy is a plugin to copy the literal values. Smart Copy action maps to Ctrl+Alt+Shift+C by default. It copies the value of compile time constants and String literals to the system clipboard. It also copies the selected literals. Entire expression is copied if noting is selected. If it cannot do smart copy, it will fallback to regular copy action. Certainly a candidate for your Ctrl+C mapping.
