The delete key on a computer keyboard is typically located in the upper right corner, adjacent to the end, home, and page up keys. It plays a crucial role in text editing, allowing users to remove characters or entire words with just a press of a key.

When pressed, the delete key performs different functions depending on the context. In text editors, it typically deletes the character to the right of the cursor, while in word processors, it deletes the character to the left. This key is particularly useful when making corrections or revisions in a document.

In addition to deleting individual characters, the delete key can also erase selected text, files, or folders. When combined with the Ctrl or Shift keys, it can remove text in larger chunks or even move files to the recycle bin. This versatility makes it a valuable tool for managing files and text efficiently.
