keyInSelect has a limit of 35 array elements

I have to display a huge list of directories so that the user can choose from one of them. What is the reason for the limit of 35?

Hi @smks, thank you for the comment.

• For the user, the list should not be too long. The size of many terminal windows is small, then your app should have a pagination (like more command) to show the long list.
• keyInSelect is used for simple interface. 0 .. 9, A .. Z keys are found easily by user.
• The keys other than the 36 keys (includes 0) are not many, if you want to receive multiple keys such as the item number for long list, you can use questionInt method. But I think that it's not good idea as I said. The list should be split. For example: https://github.com/anseki/readline-sync#itemscount

I decided to use a columnify npm package, and built 4 columns of options to format and compact it a bit better. I then use a questionInt to grab the index. Great package by the way!
