Gets emitted when the user initiates a cursor movement.
The move_cursor signal is a [keybinding signal](class.SignalAction.html). If the cursor is not visible in
entry, this signal causes the viewport to be moved instead.
Applications should not connect to it, but may emit it with emit_by_name if they need to control the cursor programmatically.
The default bindings for this signal come in two variants, the variant with the Shift modifier extends the selection, the variant without the Shift modifier does not. There are too many key combinations to list them all here. - Arrow keys move by individual characters/lines - Ctrl-arrow key combinations move by words/paragraphs - Home/End keys move to the ends of the buffer
