Hello. The other day @ABG suggested me to work with dictionaries instead of lists. I read some tutorials and discussions (MIT App Inventor Dictionary Blocks, Dictionaries and JSON) but didn’t understand very well how it works. Most of the examples put text as a key and I needed to know if it was possible to put buttons. Doing trial and error I discovered that it was possible and decided to make a keyboard to see how it works. Here I include the blocks and the aia, in case it helps the rest of the readers. If there is an easier way, please let me know.
