'goto_tray 4' Will put tray 4 in place of tray 1.
I'm not looking to put any tray in place of tray 1 (or 2, or 3), but rather to open/close a 4th tray (much like when I click on the "+" right next to "Recipes").
/toggle tray1
The original 3 trays are actually 1 unit, called Tray.
Each extra bar that is added by the "+" can be toggled by the names "tray1, tray2, tray3, tray4, tray5, tray6, tray7, tray8", based on the order in which they were originally opened when pressing "+". Once you figure out what your 4th bar is named, it will always be toggled by that same tray number, regardless which powertray is actually displayed in it.
If you only ever opened one extra tray, it's probably just tray1, so your command to bind it to a key would be:
/bind KEY "toggle tray1"
Works like a charm, perfect. Thank you !
Is there a way to bind the opening/closure of a 4th power tray to a key? I've tried looking around, but can't find (or understand) an answer if there is any.
