IntelliJ idea set code hints or auto-complete shortcut keys

For Java developers in China, the most likely people to use eclipse.
There are a lot of programmers who use idea, and everyone is advocating it.
Try half a month, feel the same, the key to see proficiency and configuration is good.

Sometimes you want to use auto-completion, because a non-lazy programmer is not a good programmer. But the default shortcut for idea is Ctrl + space. For ordinary people who install the Chinese input method, that's the cup, you know.

Here's how to modify it:

Click on the File menu (files) –> click Settings (Settings ... Ctrl+alt+s),–> Open the Settings dialog box.

In the left navigation box, click KeyMap.
Then select Main menu–> code–> completion in the tree box on the right.
Then there are two things to do:
1. Remove the alt slash shortcut binding for the original cycle Expand Word.
2. Right-click on Basic, remove the original CTRL + Space binding, then add Alt + slash shortcut.

Then apply, OK.
