When you edit a line you have the opportunity to change the name of the line, and also whose line it is.
The Line editing screen appears as below with the current line name shown in the name field.
You can select a new character for the line just by pressing one of the characters shown, though if you are moving all of a persons lines to another person it can be done in one go on the Characters screen.TOP TIP: If you want to easily rename a line and have an device with voice to text on the keyboard, use the microphone button on your keyboard. Then just say the start of the line and it will put it in the name.
When you edit a stage direction, you will see the same screen. The character image shown will be the same as the one used for Them, but changing it won’t have any effect.
