From Eclipse to Intellij Idea, you need to set the shortcut key settings, eclipseintellij

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

The modification method is as follows:

Choose File> Settings... Ctrl + Alt + S),-> open the Setting dialog box.

In the left-side Navigation Pane, click KeyMap.
Choose Main menu> Code> Completion in the tree on the right.
Next we need to do two things:
1. Remove the Alt + slash Shortcut Key Binding of the original Cycle Expand Word.
2. Right-click Basic, remove the original Ctrl + space binding, and then add the Alt + slash shortcut.

Then Apply, OK.

In intellij idea, the query method is redirected back and forth, which is crazy when you don't know the shortcut key.

The shortcut key in key map is displayed.

Enter "keymap" in the search box on the left, search for keymap, click it, and enter "Navigate" in the search box on the right. A Back forward under the Navigate directory is displayed.

Back to ctrl + alt + ↓ or button4 click

Forward ctrl + alt + → or button5 click

Remove the original binding and add your shortcut key.

Ctrl + HOpen the class hierarchy window and use Ctrl + B/Ctrl + Alt + BCorresponding to the parent class or parent statutory and sub-class or sub-method implementation, view all methods of the current class Ctrl + F12.

It is easy to use classes or methods,Alt + F7. To find the location where the text appears, useCtrl + F/Ctrl + Shift + FSearch in the current window or in the whole process, and then cooperateF3/Shift + F3Move the cursor to the next match.

Ctrl + Shift + F global search eclipse alt + h

Ctrl + Shift + r replace eclipse alt + f globally

Alt + f8 view the value of the selected expression (ctrl + u for eclipse)
