I'm setting a TextArea object to be editable with a menu selection to allow a field to be updated by the user.
The callaback to do so works fine but it is annoying to have to manually select the text area to get it to have focus and then do the edits.
Is there any way programmatically for the menu callback function to shift focus to the textarea object?
This is in an AppDesigner application.

Yes, starting in MATLAB R2022a.
Use the new focus(c) function to set focus to a ui component c. This MATLAB release also provides additional resources to control the focus order of ui components in AppDesigner.

You may be interested in the R2022a prerelease. And while you're looking at it, you may be interested in typing >>doc focus

That will be a boon, indeed, @Sean de Wolski.
I generally upgrade only once/year and have pretty-much stayed with a previous year b release...no real reason other than rarely need "bleeding edge", just habit.
