How does dota2 set the traditional key for quick casting?

Dota2 supports rapid casting, but does not support automatic rapid casting according to the traditional key position setting, if you want to do so.

Every time you play with a different hero, you have to go out and tune it. Traditional keys do not support fast casting because it is very, very troublesome.

And basically every user who casts spells quickly is a player who is used to fixed keys such as Q, W, E and R, and no Dota veteran needs this thing.

Rapid casting setup

The key for quick casting is empty by default, and it is in the same interface as the key for skill (the key for skill is on the left and the key for quick casting is in the lower right corner).

One thing to note is that if the skill key and the quick cast key are duplicated, only the key you set at the latest will take effect.

But you can also press and hold one of the two keys Alt and Ctrl to set it.

Example:

Captain's traditional key position t

Quick casting (Ctrl+T) or (Alt+T) is to hold down an auxiliary key and then press the skill key, which is equivalent to quick casting.
