If you learned DotA 1 on a standard QWERTY keyboard, you know the drill. Your spells were mapped to (and sometimes V or B, depending on the version). Your items? That depended entirely on which slot you put them in. And the most controversial slot of all was the top-left corner: Inventory Slot 1 .
Imagine a teamfight. You are playing Sand King. You blink in, channel Epicenter. The enemy stuns wear off. You need to activate your BKB (Slot 1, Hotkey A) to avoid the follow-up magic burst.
The problem? was a sacred cow. Even if you remapped your hero's Spell 1 away from A, the underlying Attack command was hard-coded into the game engine. You couldn't delete it. You could only overlay it.
You just lost the game. This led to a massive schism in the DotA 1 community. Two camps emerged: dota 1 hotkeys inventory a
It created a unique stressor. When you had a TP scroll in Slot 1 (bound to A), you would constantly hold your breath as you tried to teleport away from a gank. If you pressed A on the ground instead of A on the minimap, your hero would turn around and walk into the enemy team. When Dota 2 launched, Valve mercifully severed the link between attack-move and inventory. In Source 2, "A" is just for attacking, and items can go anywhere (D, F, G, Mouse4, etc.) without conflict.
For many custom keybind setups (particularly the popular "Warkeys" or "Customkey.txt" modifications), the default or most common binding for that slot was... . The Attack-Move Conflict To understand the friction, you have to understand the Warcraft III baseline. In standard WC3, "A" is the universal hotkey for Attack-Move . You press A, left-click the ground, and your hero walks to that location, attacking any enemy they see on the way. It is a fundamental, non-negotiable command for micro-management.
But your muscle memory slips. You press A... and instead of activating your godly immunity, your hero issues an attack-move command . Sand King, mid-Epicenter, suddenly stops channeling and starts waddling toward the enemy carry to slap them with his tail. If you learned DotA 1 on a standard
Specifically, let's talk about the letter
Before the polished esports arenas and the standardized QWER layouts of Dota 2 , there was the Warcraft III engine. And within that engine lived a specific point of contention for every veteran player: the inventory hotkey situation.
These players never touched custom keys. They clicked their items with the mouse. It was slower, but safe. They thought binding items to letters like A, S, or D was a sign of weakness. "Just click the icon," they'd say, as they fumbled to double-click their TP scroll. That depended entirely on which slot you put them in
So what happened when you mapped your or your Black King Bar to "A"?
Next time you casually press "1" to use your Blink Dagger in Dota 2, tip your hat to the old-timers. They had to ask themselves every single game: Do I really want my BKB on A?
The most elegant solution was to bind inventory slot 1 to a different key entirely—often or a mouse button. But for those who didn't know better, or who used pre-made configs from forums like playdota.com , "A" for item slot 1 was the default. Why "A" Was Actually Good (For Certain Items) Despite the risk, some players swore by the "A" key for specific items. Why? Speed.
