Best method for hot key remaps for Shader controls

[flagrant99]

retroarch.cfg

Applies next and previous shader in directory.

input_shader_next = "m"
input_shader_prev = "n"

So I want to remap these guys to
input_y + Hotkey
input_a + Hotkey

These are not currently mapped to a hot key in combo button press in librettro.

My autoconfigs have
input_load_state_btn = "5"
input_state_slot_decrease_axis = "-0"
input_state_slot_increase_axis = "+0"
input_exit_emulator_btn = "9"
input_save_state_btn = "4"
input_enable_hotkey_btn = "8"
input_menu_toggle_btn = "0"

Can I add in autoconfig?
maybe input_next_shader="1"?
Or do I edit retroarch.cfg to some how handle hot keys?
I can go into RGUI and set. It works. BUT.
how should I save?

I've gone into RGUI and mapped the new hot key binds, but not sure hot to save.
Will these mess with my other default hotkey binds?
I want those left alone.

@flagrant99 yeah, you'll want to set this in the autoconfig. To bind a controller button, you need to add the _btn suffix, like so:

input_shader_next_btn = "{n}"
input_shader_prev_btn = "{x}"

...where {n} and {x} are numbers that correspond to the controller's button assignments.

(_axis binds an analog axis, and [no suffix] binds a keyboard key.)

Add the input_shader_next_btn and input_shader_prev_btn lines and use the same numbers as your input_y_btn and input_a_btn settings, to use those buttons for the hotkey functions.

@sleve_mcdichael Thanks worked great.
