   I got annoyed with kbdcontrol's inability to put returns or tabs in 
macros (makes it difficult to do multi-line commands. :), so I patched it 
to handle \ notation..

  kbdcontrol -f 1 "cd /\nls\ncd\n"
works admirably to create a sequence of:
cd /
ls
cd

   Minor tweak, but it was bugging me that it wouldn't work. The 
disadvantage is that if anyone uses \s in their current keyboard macros, 
they'll have to escape them with \\.  I can't see anywhere that the 
changes to kbdcontrol would cause any problems except that.  I also left 
out the other standard escape characters, because I figured that those 
three are all you really need in a keyboard macro.  Easy to insert them 
later.

This is a diff off of FreeBSD-stable (as of today), which is identical to 
-current's kbdcontrol.
