Camtasia 2020 - Auto-Resize Text Toggle
Gives the users complete control over text callout position and font. Instead of resizing the font when a callouts dimensions are altered to fit, this checkbox allows the user to adjust the font size or number or words without changing the x, y position or dimensions of the callout text area. If too much text is typed, or the font size is too large to fit in the text area it will be clipped (hidden) from view. It then falls on the user to resize the callout dimensions to make the text visible.
The auto-resize text callout is a huge benefit for users doing their own layout who wish to get consistent positioning and font sizes. Super useful when text is left or right aligned in the text box.
