Steps to reproduce:

1. Hold down the backspace key (or any other key) in the search box.

What happens:

Only one character gets deleted.

What you expected to happen:

After a short time, multiple characters should start being deleted.

Version (make sure you are on the latest version before reporting):

Minecraft: 1.2.12
Forge: ToT
Refined Storage: 1.5.34

Hm.. when I build RS and run it from gradle, I can't repro the issue.

However, I can reliably repro on the Direwolf20 1.12.2 pack with an updated RS and forge. It also repros with the standard RS and forge that ship with the pack, and when all mods except RS are disabled.

I figured out how to repro it from my gradle client:

1. Load up a world in creative mode with JEI cheating enabled
2. Set JEI cheating to false
3. Try to type repeated characters in the pattern grid

Ah, I assume that's a flag that's by default on, but anyone can toggle it and it won't be untoggled.

So I need to assume that it'll be always untoggled and toggle the repeated key events on in any case.

This works for me:
