because when ever press shift + Scroll mouse it's horizontal scrolling in Macintosh , so the bar switch with mouse did't work . Only the Shortcut key work on Mac . can you add a switchable key binding like Alt key does.
pls.

Fabric 1.17 release has an option that disables sneak to display full inventory by default and adds a keybind to replace sneaking. Will port to forge when 1.17 is out.
