Question: Where are the capital letters?

Answer: 

Capital Letters are found in three ways. 
  1. Tap the Capitalization icon (Aa) on the toolbar and the alphabet will become capitalized.  
  2. Within a pallet tap the Aa in the upper left corner to capitalize the first letter when desired tile is pulled out onto the desktop. (Exceptions are Endings, Suffixes and Symbols) 
  3. Double-tap anywhere on the desktop and the alphabet will become uppercase letters. 
After the first tile is pulled off they will default back to lowercase letters
