Prior to 1.19.4, when you have the crafting UI open and the recipe book panel has been expanded, pressing 't' focused the search field. This stopped working in 1.19.4. It was a very handy feature.
Note that this only affects survival mode. The creative mode inventory still switches to the search box when you press 't'.
