Further information from me:
In Corel Draw, LMB does not select locked objects, but RMB does and displays a context menu that allows one to unlock the object. Most of the time it's useful because the usual way of doing things is to first select and then right-click to bring up the menu. As a side note, the context menu is actually context sensitive in Corel Draw, e.g. the items depend on what's selected. We could also use this - e.g. add an option "put on path" if a text and a path is selected, or a submenu "boolean operations" if more than 2 path-convertible objects are selected. This information could even be added to verbs so that each verb knows what objects it has to have in order to complete successfully, and a list of matching verbs is built automatically.
To the original poster: Currently to unlock an object you have to use the Find dialog.
