Delphi toolbar button to switch between unit and form view disapppeared?

Question

Two buttons on the view toolbar in Delphi disappeared and I can't get them back. One of those buttons is the one to switch between code/unit and the design/form view which I use all the time. The keyboard shortcut for switching (F12) still works, but I have one of those pesky media keyboards where you have to press a function key to access F-keys, so I'd really like to get that toolbar button back.

I tried resetting all the toolbars and their contents, and I see space where the buttons should be, but they aren't there. In the customize dialog for the toolbar, the commands don't seem to even be there anymore.

I tried doing a "repair" re-installation of Delphi, but even that didn't fix it. Has anyone else had this happen before, or have ideas on how to repair or reset my IDE?

edit: perhaps it's worth mentioning the menu options to toggle between code/unit and design/form view are also missing.

Answer 1

As best I can tell, this problem (missing view unit/form button and menu option) could possibly be a limitation of the starter edition of Delphi (this forum post: https://forums.embarcadero.com/thread.jspa?threadID=83324 ) seems to indicate an XE3 user with starter edition has the same missing buttons on their toolbar.

I did discover at the bottom of the screen there are tabs to switch between code, design, and history, which does at least give a mouse-based workaround to toggling between the views without having to expand the file view and click the right pas/dfm file. And the F12 keyboard shortcut does still work as well.
