Description
-----------

LineEdit provides a single-line string editor, used for text fields. It features many built-in shortcuts which will always be available: (the Ctrl here maps to Command on macOS)

- Ctrl + C: Copy

- Ctrl + X: Cut

- Ctrl + V or Ctrl + Y: Paste/"yank"

- Ctrl + Z: Undo

- Ctrl + Shift + Z: Redo

- Ctrl + U: Delete text from the cursor position to the beginning of the line

- Ctrl + K: Delete text from the cursor position to the end of the line

- Ctrl + A: Select all text

- Up/Down arrow: Move the cursor to the beginning/end of the line

On macOS, some extra keyboard shortcuts are available:

- Ctrl + F: Like the right arrow key, move the cursor one character right

- Ctrl + B: Like the left arrow key, move the cursor one character left

- Ctrl + P: Like the up arrow key, move the cursor to the previous line

- Ctrl + N: Like the down arrow key, move the cursor to the next line

- Ctrl + D: Like the Delete key, delete the character on the right side of cursor

- Ctrl + H: Like the Backspace key, delete the character on the left side of the cursor

- Command + Left arrow: Like the Home key, move the cursor to the beginning of the line

- Command + Right arrow: Like the End key, move the cursor to the end of the line
