DaleEltoft,
MD and
MZ are keyboard shortcuts.
Shortcuts are 2(3) letter key-in that you can use almost wherever the focus is.
Just type the 'M' key and then the 'D' or the 'Z' key.
Shortcuts use capital letters but you just use the keyboard key and thus not with the Shift key pressed.
If that is required then it is mentioned e.g.: Print Preview (Ctrl+Shift+P)
See:

After typing
MD with the focus on the drawing area you will see that the command in the Command History is '
duplicates'.
That is the same when activating it with the Modify Toolbar button or with the Modify menu tool button.
Most common drawing tools have a command that is identical to the shortcut.
That is not the case for these tools, see: App.Prefs. .. General .. Tool settings.
And sometimes it is conflicting:
Draw .. Line .. Line from 2 Points:
- - Shortcuts: LI
- Commands: 'line' ; 'ln' ; 'li' ; 'l'
Draw .. Line .. Orthogonal/Tangent:
- - Shortcuts: LN
- Commands: 'lineorthogonaltangent' ; 'orthotangent'
One can not use the command '
ln' for the latter because that is taken by Line from 2 Points.
(BTW: You don't see me entering the commands of this tools in the Command Line

)
Bottom line: In general you don't enter the key-in shortcut in the Command Line.
