Home键是一个于IBM/Windows键盘上的按键。

HOME键和END键正相反，若只单独按HOME光标则会定位到本行的最前面，如果按CTRL+HOME键，光标定位到文档最前面。。当按下Home键时光标移到一行的开头或移到网页的最上方。

The Home key is commonly found on computer keyboards. The key has the opposite effect of the End key. In limited-size keyboards where the Home key is missing the same functionality can be reached via the key combination of Fn+←.

Its standard symbol ⇱ from ISO/IEC 9995-7, i.e. an arrow pointing to a corner in the upper left, is used on some full-size keyboards instead of a possibly localized text label.
