What inspired this Wish List Request? Putting more effort than I should into drawing perfect circles and perfectly straight lines 
Please describe the new or improved feature or solution you would like to see. JMP already uses the Shift key to allow for resizing graphs while retaining the aspect ratio. It would be nice to extend this to the different annotation features to allow for drawing perfectly straight lines and perfect circles while just holding the Shift key.
What would the value be to you and/or other users if this new feature is provided? Simple quality of life improvement when annotating
Is this an external customer request? No
Is there a competitive software package that has this feature or solution that we should be aware of? Programs such as Powerpoint, PowerBI and Adobe
Will this impact a renewal, expansion, or adoption at a customer, and does this put an account at risk if we do not address this? No
