Welcome to the community!!

Here's an example that may help you.

> Curious the best way to go about this. I want to restrict a text input to a specific length, must be 6 characters (no more, no less), and each position is restricted to certain characters. For example, the first position can only have C,E,F,G,V. The 2nd-6th will have similar restrictions. I’m assuming I will use the key press event? Anyone have any additional tips or help? Thanks in advance.
