paste on all characters

Hello,

I need to create a font where all characters have a vertical line right to the normal character. I can open one character, and paste my vertical line, and so one for the others, but it will take time. Is there a way to have a global paste (on all character), the existing one replace the character, and I want to add the line to the existing character.

Thanks for help.

I don’t think there is any way to do this. Scrolling to the next character using the keyboard is a bit faster than using the mouse — the shortcut is Alt Right.
