In modern Microsoft Windows text editing applications, it is primarily used to return the cursor to the beginning of the line where the cursor is located. When the text is not editable, the Шаблон:Key press key is used to return to the beginning of the document; this can also be done in editable text if the key is pressed along with Шаблон:Key press.
The Шаблон:Key press key can also be used to select all the characters before the cursor in a certain line if pressed along with Шаблон:Key press in selectable text.
macOS
Only full-sized Apple keyboards have a Шаблон:Key press key. In macOS single line text fields, the key works like it does in DOS and MS Windows, going back to the days of dumb terminals, where Home moves to the start of the line. In multiline word processors, when the key is pressed, the window scrolls to the top, while the caret position does not change at all; that is, the Шаблон:Key press key is tied to the current window, not the text box being edited.[1][2] On Apple keyboards that do not have a Home key, one can press Шаблон:Key press for the Home key functionality described above. To get the same result as the Windows platform (that is, moving the insertion point to the beginning of the current line of text), one can press Шаблон:Key press. An application can also be used to change this behavior.[3]
Linux
In Linux, the Шаблон:Key press key has basically the same functionality as it does on Windows. It returns the cursor to the beginning of the line in editable text, and otherwise scrolls a scrollable document to the beginning. Also, like Windows, the Шаблон:Key press key can be used to select all the characters before the cursor in a certain line if pressed along with Шаблон:Key press in editable text.
