Selectors can be created for some things in KMD Institution without issues, including from the main menu, in other places it is more stable to use send keys.
In the main menu, controls can be made without problems.
Under Institution / Group, it is easiest with a hybrid approach. Marked in red are examples of controls that can be created, and marked in blue are things that are better suited for Send Key actions, as the selectors that come with controls do not work, as of version 9.10.3 in KMD Institution . If you press Alt , you can get shortcut keys for the main menu, which can also show and execute the menus that are marked in the main line, marked in orange for example.
