Pressing F3+T to reload resources in the main menu isn't possible, which poses a challenge when editing an enabled resource pack. Each major or minor change requires a resource reload for the adjustments to take effect, meaning that without the F3+T shortcut, the workaround involves either disabling and then re-enabling the resource pack, or entering a world and then using the shortcut. Both are tedious, and unnecessary.
Steps to Reproduce:
Enable a resource pack (if you do not have any, a 'dummy' pack is provided)
Enter the game's homescreen
Press F3 + T to reload assets
Expected & Observed Results:
❌ - The hotkey does nothing, and no assets are reloaded
✔ - The hotkey would properly reload all of the games assets
Can confirm as of 24w09a. Note that F3 + T does not seem to work when viewing any kind of menu.
