Version: forge-1.18.1-0.5.2

There is a conflict issue with Minecraft default sneak (Left Shift) and sprint (Left Control).
If you have any binding that use a combination of those keys, actions will be blocked.

Example: attacking, mining, placing a block while sneaking.

Like you mentioned in issue #8 removing all mod binding using those keys will help.

However, even Minecraft default bindings are effected by that: the shortcut RC+Q to drop a stack get blocked by the sprint binding.

Spamming actions or doing a different timing sometimes get pass the issue.

Encountered the same issue

True if i'm sprinting or sneaking sometimes i cant use ftb ultimine and need to let go of shift or ztrl

Same issue i cant always attack when im sprinting at mobs using ctrl with this mod, i know you can double tap, but its a lot more effective, being able to ctrl sprint + attack is essential for me double tap w is too clumsy.

I've also encountered this issue, and as much as I like JEK, I'm gonna have to switch back to controlling, until it's fixed.
