You can use the Home key if your cursor is at the end of the word. Use the End key if you place the cursor on the left side of the word.
The Home and End keys are called the function keys. They act as functions and do not produce characters when pressed. Function keys move the cursor when you are creating or editing a document. The Home key moves the cursor at the beginning of a line in a word or a sentence and the End Key place the cursor at the end of the line.
