I realized that there is an important difference: the "-" four times (which is the hrule macro) draws the line till the margin (minus 5 mm), while the assignment I wrote (which is perhaps better written as a macro: <assign|minus-sep|<macro|<with|line-width|1.25ln|<line|<point|0par|0.50ex>|<point|1par|0.50ex>>>>>) draws a line of 1par length regardless from where the line begins (so it can go beyond the margin).

So the hrule macro, the one invoked pressing four times the "-" key, may be better. It can also be adapted, e.g. <assign|red-hrule|<macro|<with|color|red|<hrule>>>>, but probably to change line style and dashing one needs to change the hrule itself (which is in turn based on the datom macro).

Yes Giovanni, It's quite the same except this is just a kind of shortcut.

This shortcut is very nice.

I figured out that it is either the same or almost the same as


<assign|minus-sep|<with|line-width|1.5ln|<line|<point|0par|0.5ex>|<point|1par|0.5ex>>>>
