I am looking for a keyboard shortcut that selects the full line (i.e., the text of the line) of the blinking caret cursor in any editable, multi-line text field. Nothing more than just this one line should be selected.
I understand that one can use the following two keyboard shortcuts in succession to accomplish this:
shift + ⬆
shift + ➡
However, this does not work in all applications. That is, sometimes this combo highlights the current line plus the previous line, minus the first character of the previous line.
