On any open session in ICANotes, you can utilize the function from the main file menu, which is located at the very top left of the program. 

 

Click into the View menu, as depicted below, then select the option to either Zoom In or Zoom Out. 

 

 

As you make a choice your session will adjust accordingly. 

 

Example: Zoom In from default size

 

Example: Zoom Out from default size

Your account will remain at that size for the remainder of your session, but will default back to the original size the next time you login to your account.
