Flat offers a large set of actions that you can perform. At some point, it can become simpler to apply these actions. Here’s how to do a perfect range selection.
Using the Mouse
The logic behind is pretty much the same as you can find on any well known text editor. To start a selection hold the mouseleft button. Keep the mouseleft button hold and move your mouse to the end of the selection you want to set. That’s all you can now copy / paste for example.
Using the Keyboard
Again the logic behind is pretty close to text editors. When you start to hold shift a virtual “anchor” will be placed where your cursor is. Then using the keyboard arrows you will be able to move the cursor around and create a range.
|⇠||Extend the range to left|
|⇢||Extend the range to the right|
|⇡||Extend the range to the upper stave or part|
|⇣||Extend the range to the lower stave or part|
