Ability to Set Multi-key Keybinds

[pschlik]

As someone who hails from MSTS, the default control scheme in SimRail doesn't really vibe with me, and when changing things to match what I'm familiar with, I was disappointed to find I couldn't rebind a control to use a combination of keys. Even if multiple keys are pressed, the game will take the first key it detects and use that as the binding. This prevents me from eg setting the master switch binding to Ctrl + W; if I attempt to do that the binding is assigned as just Ctrl (and it can't be W as I use that to set reverser forwards, and you aren't allowed to have one key on multiple binds.)

Gaining the ability to have combinations of key presses drive keybinds would make control on keyboard so much more flexible and is practically a requirement for things with more controls to manipulate (particularly steam locomotives). Considering every function has to be given a unique key, I'm pretty sure I'd run out of regular keys and start using F7-F12, Pg Up/Pg Down, and other utility keys if I had to make a steam locomotive control layout in the current system.
