What?

The ability to define a custom hotkey prototype so that it is always bound to the same key as a predefined built-in hotkey.

Whaaat?

For example i would like to get an event each time a player attempts to clear the cursor. This defaults to "Q" currently. So my current workaround is to define a custom-input that also binds to "Q". But i have no way to guarantee that my custom-input and the "clear cursor" built-in action are always bound to the same key if the player rebinds one of them.
The custom-input could show up in the mod-hotkeys menu either as an uneditable hotkey or simply not be shown at all (the latter is probably preferable from an "avoid player confusion" point-of-view).
"Simply" raising a moddable event for all built-in actions would work too, but might cost more performance?

Why?

In my mod i need to detect if and when a player attempts to clear the cursor even if the attempt fails due to full inventory. Also there are probably a number of similar cases where a mod function is logically bound to a certain input action.

So essentially "lua callbacks for all keyboard-triggered events" if I understand you correctly.

Or to be able to add Lua listen events to keybinds via less intrusive methods, maybe Get_Hotkey(drop_item) would return the hotkey for that and it only has to be run when hotkeys change as you can use it as a parameter to do the normal Lua listens

Yea. Like i said. Either raise events for everything or allow linking. The effect is the same. But i wouldn't know which way is cheaper on performance.

@Any moderator:
I just noticed i posted this in suggestions instead of "modding interface requests". Could anyone be so kind and move it?

I've added support to link a custom-input prototype directly to a game control for 0.16. When a custom-input is linked to a game control it won't show up in the control-settings GUI and will fire when the linked control is pressed.

Rsed to the rescue! Thanks a lot again!

Can you supply example code? Or is it sufficient to do something like: Also can i still fetch the button name for localization from the linked custom hotkey, or do i need to fetch it from the link target?

You just leave key_sequence as an empty string or w/e - it doesn't matter - it won't be used except if you try to use it in locale. You define "linked_game_control" as the game key you want it to link to so "clear-cursor" in your example. You'd need to use the locale for "clear-cursor" since the game will ignore what ever you've defined for the custom input.
