Special time signatures
In MS2 it is possible with Time Signature Properties to use certain "Other" symbols. It is also possible to delete the lower number (the second box) and have the upper number presented vertically centred. I use both these features (typically in early music). Neither of these work in MS3.

Try entering a space in the second text entry box. It may depend upon your OS and upon the keyboard layout you have selected. I'm using ubuntu studio and have my keyboard set up as English (UK International with Dead Keys). I can get the first symbol by entering [AltGr][Shift]O and the 3 on its own by entering 3 in the first text box and a space in the second,

ALT+0216 deals with my first symbol, but it gets a denominator. I can't get a space into the denominator box.
I'm using Windows 10.

I've found the answer.
I was using right-click on the time signature and Time Signature Properties - can't enter a space that way.
But using Create Time Signature in Master Palettes I can create the desired signatures.
