would be cool for this to be a feature, e.g. binding RB + LB to take a screenshot, or RT + B to open up the backpack from your Backpacked mod

seconding this- Midnight Controls has implemented multi-button bindings but is only on Fabric, impossible to play with controller with mods like "Parcool" as there are not enough key binds. thanks for all your hard work.

Already possible with radial menu in the mod

Thank you so much for taking the time to respond. Just to clarify, the radial menu opens and you have to choose an option with the joystick, right? This is fine for the initial examples (e.g. screenshot, menu, inventory, etc...). But for movement mods like parcool, there are multiple types of movements that require quick pressing of different buttons (e.g. jump then grab ledge). This is compounded by the fact that keybinds don't work when there is a conflict (so for the example above, I sacrificed "quick move" for moving items so I can have a button for "grab ledge"; I also sacrificed D-pad down "drop item" for "crawl"). If I was able to, for example, use "B" button as the initial press followed by "ZR" for grab, this would all be doable in rapid succession after jump (and for example, use "B" and "ZL" for wall run).

Please let me know if I am missing something about how to use radial menu to achieve the above. Thank you again for your time and all the work you put into your mods (without controllable, my 6yo son wouldn't be able to battle mowzies mobs, which gives him great joy).
