How to set defaults in form controls

Hi,

I can't seem to find where in Libreoffice Writer I can set defaults for
the font etc. in form controls. I set my default font for new documents
to Arial 11, but when I insert a form control the font there is always
Liberation Sans, Regular, 12.

I searched the web for quite some time, but the only "solutions" were to
change it afterwards by selecting all the form controls and change it then.

Where can I set the default for the font and other properties?

Thanks
Thomas

I use Writer 5.1.4.2 and in that version 'Default Fonts' are listed in
Tools > Options > LibreOffice > Advanced > Expert Configuration >
org.openoffice.VCL > Default Fonts > en

There you will find a list of some 22 properties. I don't know which you
need for form controls.
In each case, the first font listed is the one that is used by default.

I have recently edited LATIN_SPREADSHEET to change the default font in
new spreadsheets but I repeat that I do not know what the property is
that you need for form controls.
