space for text lines

hi,all

I know that we can use (setvar "textsize" *) to set text default height.

everytime I should use command "mtext".

then pick a point.type "L" option and lines space type(at least) to set text lines space (0.8x).it is annoy.

so if I want to set default text lines space.which codes should I use?

see the picture.

I use this reference because, even though its for 2006, its easy to use the Find functionality in most browsers.

I dig into it more, is it possible to set the text background mask as the current background color by default??not transparent.

The SYSVDLG command is also quite useful.
