SnowfallKeyPress 1.0.0 is a small WotLK input addon maintained in the historical package by Dayn. Its purpose is specific: supported keyboard bindings are activated on key-down instead of waiting for the key to be released. That reduces the delay between pressing a bound action and sending it to the game; it does not change spell cooldowns, the global cooldown, or the spell itself.
What it changes
The addon accelerates bindings rather than every possible mouse click. The historical WotLK description covers normal keyboard keys and mouse buttons 3-5, including modified and unmodified combinations; PRINTSCREEN is excluded from the default set. Mouse-wheel bindings do not need a separate acceleration setting because a wheel tick is already a press-and-release event.
This is useful for a player who wants a healing, dispel, interrupt, or PvP action to be sent as soon as the key is pressed. It works with action-bar key bindings, but it does not turn an unbound click on an arbitrary frame into an accelerated action. In particular, direct click-casting clicks handled by Clique or VuhDo are not accelerated by SnowfallKeyPress.
Configuration workflow
Open the WoW Interface -> AddOns options and select SnowfallKeyPress. The configuration panel can enable or disable acceleration globally, clear the current list, add or remove an individual key or mouse button, and add all modifier combinations for a key. To restore the package defaults, use Reset To Defaults. For a controlled setup, clear the list first, add only the keys used for important actions, then test a heal, dispel, or interrupt on a target dummy before using it in PvP or a raid.
Version limits
This is the old WotLK 3.3.5 package, not the later Retail "Snowfall" button-flash project. It changes input timing only and cannot bypass Blizzard's protected-action or combat-security rules. The package has no confirmed slash command; use the Interface options. Install the addon folder under Interface/AddOns and enable it on the character-selection screen.
