Hi Romuel! Thanks for your question. Lucidchart has a few keyboard shortcuts to facilitate object manipulation, including options for copying, zooming, and text editing. A full list of these shortcuts can be found at here. Currently, a dedicated shortcut for locking objects is not supported within Lucidchart. But Lucid values user feedback and requests! To submit a feature request, first search the Product Feedback section of the community forum, utilizing the "Idea" filter. If a similar request exists, please contribute your additional details and upvote the existing submission. By grouping similar feedback together, Lucid can better understand what features users really want and how popular those features are. If a shortcut for locking objects has not already been requested, create a new submission, including details about your use case and desired functionality. This allows other users with similar needs to discover and support your request. For further information on how Lucidchart manages community feedback, please refer to this page. Good luck!
