LeetCode Submitter is a free Chrome add-on developed by walkccray. It is designed to restore the shortcut key functionality for code submission on the LeetCode website. Previously, the website supported the use of shortcut keys to quickly submit code, but this feature was removed for unknown reasons. With LeetCode Submitter installed, users can once again use the shortcut key combination of ctrl+return to submit their code effortlessly.

In addition to the code submission shortcut, LeetCode Submitter also introduces a new feature. By pressing ctrl+`, users can conveniently close the 'x' and toggle the Console panel, enhancing the overall user experience. The addition of this feature allows users to navigate the LeetCode website like a pro.

LeetCode Submitter has undergone several updates to improve its functionality. In the latest update, deprecated 'keyCode' has been replaced with 'key' for a more reliable performance. The shortcut key combination of ctrl+x can now be used to close the 'x', while ctrl+c can be used to toggle the Console panel. These updates ensure a smoother and more efficient user experience.

If you are a LeetCode user who misses the convenience of shortcut keys for code submission, LeetCode Submitter is a valuable add-on that brings back this functionality and enhances your overall coding experience.
