I cannot open up the symbol gui when sneaking and right-clicking. On your "Chalk Mod Showcase" video, a commenter has the same issue and I'm unsure if my lack of modding knowledge is the issue here.

I've unbound and rebound my sneak key but that doesn't appear to fix it; is there anything I should/shouldn't be doing?

(love this mod btw, rad work)

Ah I knew I was being dumb haha! Thanks for the help! Love this mod!

Please provide more information: what version of Chalk you have installed, version of forge and minecraft.
Is there anything in the logs? (errors, warnings, etc)

I have the 1.18.2 version of Minecraft, the 1.4.2 version of Chalk and the Forge version 40.2.0. As far as I know, there are no warnings or errors but I am fairly inept when it comes to this stuff so I could be missing something blatantly obvious without knowing.

Additional symbols were added in 1.5.0 update, which is only in 1.19.2+.
