- Declare this as a variable called "Temp1"
Aside from not knowing what "this" is, what's stopping you?
- Have a second button pressed and printed to (1,1)
You are going about this all wrong. The getKey() method is not a blocking function. That is, it does not wait for a key to be pressed.
You need to collect key press data in loop(), whenever it happens, and then call that function to display the key pressed, at the appropriate location.
