type a word on the line without desturbing the line

[Bermuda Mama]

I am using Outlook Publisher and I need to know how do I type on a line
without desturbing the line.

Not sure I understand.
Do you want to overwrite a line of text?
If you want to add a word without the line moving, use the character spacing option
in the format menu.

Are you using Outlook or are you using Publisher?
