@Martin Schmelzle An initial implementation. May need adjustment as per your needs:
direction = 'down'
activeEditor = matlab.desktop.editor.getActive;
currentPosition = activeEditor.Selection(1:2); % Assuming no selection for simplicity
switch lower(direction)
case 'up'
newPosition = max(currentPosition(1) - 1, 1); % Prevent moving above first line
activeEditor.Selection = [newPosition, currentPosition(2), newPosition, currentPosition(2)];
case 'down'
% You need to consider the total number of lines in the document
newPosition = currentPosition(1) + 1; % Add logic to prevent moving beyond the last line
activeEditor.Selection = [newPosition, currentPosition(2), newPosition, currentPosition(2)];
case 'left'
newPosition = max(currentPosition(2) - 1, 1); % Prevent moving before first column
activeEditor.Selection = [currentPosition(1), newPosition, currentPosition(1), newPosition];
case 'right'
newPosition = currentPosition(2) + 1; % Assuming infinite right movement is allowed
activeEditor.Selection = [currentPosition(1), newPosition, currentPosition(1), newPosition];
end
Manipulating the cursor like this might not work for all cases, especially for moving up or down, where you'd have to take into account the number of characters in the line to position the cursor correctly. Additionally, these approaches may use undocumented features or features that are not primarily intended for cursor manipulation, so they might be subject to change in future MATLAB releases or might not work as expected in all scenarios.
