Is there a Mac keyboard shortcut to "Select Current Line"?

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.

Solution 1:

To select an entire line of editable text, assuming a left justified language...

If the insertion point cursor is at the beginning of the line, press:

• Command–Shift–Right Arrow ⌘⇧➡

If the insertion point cursor is at the end of the line, press:

• Command–Shift–Left Arrow ⌘⇧⬅

If the insertion point cursor is at any other part of the line, press:

• Command–Left Arrow, Command–Shift–Right Arrow ⌘⬅ ⌘⇧➡

  Note that in this previous key sequence set, that you can keep the ⌘ key pressed while pressing/releasing ⬅ then press ⇧➡ so as to eliminate pressing/releasing the ⌘ key twice.

See the Document shortcuts section in Mac keyboard shortcuts.

Solution 2:

To move the cursor to the start/end of the line, you can use ⌘← and ⌘→.

To select whilst moving the cursor, add ⇧. You need to move the cursor to one end of the line first using ⌘← or ⌘→, then hold ⇧ and use the opposite ⌘→ or ⌘←.
