What's the problem? Describe what went wrong in few words.
Some games have a 'need to keep pressed' button, usually to run. Most resident evil games are like this and this button is dedicated. I'd like to configure a keybind to a toggle button, like caps-lock (or even if possible, any button as a toggle), to work as if the button was always pressed until untoggled. (Save load and Save state load would probably be problematic?).

What did you expect to happen instead?
This option be implemented on the key binding menu as a modifier to a key (and also allow the usual or and and conjunctions, why not).

What steps will reproduce the problem?
N/A
