Instant Preview on Lyx for package symbols?

Question

I'm using LyX, and i've noticed that when I'm using the symbols from stmaryrd (\llbracket and \rrbracket), eventhough they appear on Preview (Ctrl+R), they do not appear on the editor.

Is there a way to make LyX render them on the editor just like every other symbol (\vee,\wedge,\top,\bottom, etc)?

I think what you want is to have preview enabled. Go to Tools > Preferences > Display and change "Instant Preview" to "On". You might have to click inside your current math insets and then click outside to have them updated with the preview.

As far as having them behave like the other symbols you noted in LyX, see lib/symbols in the source code or file an enhancement request: http://www.lyx.org/trac
