Selecting non-continuous regions

The following steps describe how you can easily select non-continuous regions of text:
1. Select the first region as usual.
2. Press and hold down the [Ctrl] key, while selecting more regions.
3. When all the desired regions has been selected, release the [Ctrl] key.

A common mistake is to press the Ctrl key from the beginning, before making the first selection. This might cause things to get messed up.
