Ctrl + Shift + O
Quickly and automatically import the required packages.

Ctrl + D
Deletes the current line or selects the line.

Ctrl + /
Comment/uncomment the current line or selected line with a single line comment. It is not uncommon for some code to be temporarily closed in a debugger, so it is still quite common.

Quickly look back/forward in the current document for the selected content, although Ctrl + F is also possible, but this is more convenient.

4,   Ctrl + Shift + G
You can see where the class, method, or property that the cursor is in is referenced, which is rarely used at the moment because the code structure is simple, but will be useful in the future.
