Trong hàng loạt các phím tắt của Eclipse hỗ trợ, mình thấy có một số các phím tắt sau mà mình thường xuyên dùng và hữu dụng trong việc code như sau:

Ctrl + B : Build project

Ctrl + Shift + B: Đặt Bug, cái này thường xuyên dùng tới, bỏ đặt bug thì nhấn thêm lần nữa

Ctrl + D : Xóa dòng tại chứa con trỏ (thường là khi có nhiều dòng trống quá, ta muốn kéo code lên gom lại nhìn cho đẹp code)

Ctrl + F : Tìm chuỗi trong class

Ctrl + H : Mở nhanh màn hình search

Ctrl + Shift + O : Tự động import

Ctrl + Shift + C : Comment, uncomment một đoạn code

Ctrl + Shift + F : Định dạng format code cho đẹp

Alt + Shift + S, V : Override hoặc implement một hàm

Alt + Shift + S, V : Override hoặc implement một hàm

Alt + Shift + S, R : Tạo hàm getter, setter cho field trong class

Alt + Shift + S, C : Tạo hàm khởi tạo bằng cách override hàm khởi tạo lớp cha

Alt + Shift + S, O : Tạo hàm khởi tạo bằng các field trong class
