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

Enumerations

enum Align:

  • ALIGN_LEFT = 0 — Aligns the text on the left-hand side of the LineEdit.
  • ALIGN_CENTER = 1 — Centers the text in the middle of the LineEdit.
  • ALIGN_RIGHT = 2 — Aligns the text on the right-hand side of the LineEdit.
  • ALIGN_FILL = 3 — Stretches whitespaces to fit the LineEdit’s width.

enum MenuItems:

  • MENU_CUT = 0 — Cuts (copies and clears) the selected text.
  • MENU_COPY = 1 — Copies the selected text.
  • MENU_PASTE = 2 — Pastes the clipboard text over the selected text (or at the cursor’s position).

Non-printable escape characters are automatically stripped from the OS clipboard via String.strip_escapes.

  • MENU_CLEAR = 3 — Erases the whole LineEdit text.
  • MENU_SELECT_ALL = 4 — Selects the whole LineEdit text.
  • MENU_UNDO = 5 — Undoes the previous action.
  • MENU_REDO = 6 — Reverse the last undo action.
  • MENU_MAX = 7 — Represents the size of the MenuItems enum.
