Using the Application 
Basics of Entering Text 
You can use the TI Keyboard with the NoteFolio™ App to type 
uppercase or lowercase text by using the Shift keys or Caps Lock 
key in conjunction with the letter keys. 
If you do not have a TI Keyboard, you can also use the handheld 
keypad to enter either uppercase or lowercase text. As always, 
you press ƒ to place the TI-83 Plus in uppercase alpha 
mode, and then you can enter uppercase alphabetic characters.  
Note  Pressing ƒ has no effect on text entry from the 
keyboard, if connected. 
In the NoteFolio App, if you press ƒ a second time, you can 
enter lowercase characters. The NoteFolio App uses the following 
indicators to show whether you are entering uppercase 
, or 
lowercase text 
.
To set the correct alpha mode: 
1. Press ƒ until the indicator shows the alpha mode you 
want, either uppercase or lowercase. 
2. Press y 7 to lock the TI-83 Plus in alpha mode.
