How does dota2 just put the mouse on the attack object like LOL to avoid skills without clicking on the attack object?

Quickly cast spells and enter the main interface of DOTA2. There should be a gear button at the top left, that is, the setting button. Click to enter the settings page. Find the button settings, there are customizations, there are traditional DOTA2 buttons, and there are menus nearby. You can change the quick release button. The default is the shift+ button, which can be directly changed into a common button, so that he can cast spells intelligently, such as the little black ice sword. You just need to put the mouse on the person and keep pressing the button. No need to click the left button again.

But spells are good and bad, and some skills are still not smart. Choose for yourself.
