hello,

basically, my fastkeys in inventory, don't work. shift clicking in creative mode search, doesn't stack the item, shifting on the cross doesn't do anything either, chest looting also goes slower without shift working and that stuff, I tried looking in options, try different installations, try different settings, creating new worlds, but nothing worked.

this happened from snapshot 20w51a, and now occurs in every other version.

Hope you can find solutions, and keep up the good work!
