Lock Selection shortcut in WED?

I can't find a keyboard shortcut for Lock Selection in WED (6.40.5) - is there a way to do that, and if not, could that be added to the next version, please?

Yes, I've also found no shortcut for that. We'll add one in the next version.

While I'm asking for things, can a keyboard shortcut for "Restrict" be added to MED? (unless I've overlooked that somehow) - thanks! :-)

We'll add shortcuts for all non-menu functions. They weren't in the shortcut list so far.
