In MicroStation you can recall keyins in the keyin-dialog.
But you can not recall the last commands that you called via tools.
In competition products you get the list of last functions in the keyin no matter if called via keyin or a tool.
This is helpful if you have to repetitively go through a couple of commands.
Hello,
In MicroStation 2023 you will now be able to view and access the recently used commands in the active DGN. This new feature comes in the form of a Recents tab, which has been added to the Keyboard Shortcuts Pop-up menu. This tab can display up to 10 commands that you have recently used.

It also might not be a big deal in the first place knowing that every button is based on a key-in. So why not parse that into the Key-in window? then the user could just use the key-in window and repeat them.
