Using the menu entry Insert > Formatting > Horizontal Line I can insert a WYSIWYG horizontal line into a LyX document. I want to figure out the internal command(s) used to do this so I can set up a binding to do this via a keyboard shortcut. However, Tools > Preferences > Editing > Shortcuts doesn't show anything, and the functions listed under Help > LyX Functions doesn't show anything either.
I could make a binding to insert the \hrulefill LaTeX command, but that wouldn't be WYSIWYG.
Looking in the
.lyx file, I can see that a WYSIWYG line is done by:
\begin_layout Standard \begin_inset CommandInset line LatexCommand rule offset "0.5ex" width "100col%" height "1pt" \end_inset \end_layout
However, using a
command-sequence of multiple
self-insert to insert those lines one after the other doesn't work.
I'm using LyX version 2.1.2
