Toggle the crosshair or the entire HUD with a button, configurable keys.
I thought it was a hassle to have go to the settings every time I want to disable the crosshair so now it can be toggled on or off with a key. INI file provided to change key.
The default keys are PAGEUP to disable the entire hud and PAGEDOWN to disable the crosshair, use this site to change the keys.
Installation: Put the .ASI and .INI file in the root of RDR2.
