XEDIT maintains some sort of a 'level' parameter for each line, which
can be set by the user.  You can then select what 'levels' you want to
be visable.  You can also select whether you want 'hidden line'
messages where lines are hidden or if you just don't want to see them
at all.  So, if you added an integer 'visability' attribute to every
line in an editor, you could have it assign the level attribute
depending on how many tabs are at the beginning of the line.  This is
more flexable than a simple visability attribute.

XEDIT builds on the visability attribute with commands or macros such
as ALL /target/ which displays only lines including the target
string.

You can also choose to only see particular columns of the data and can
even look at the same column more than once.  You use the command:
VERIFY c1 c2 [h] [c1 c2 ...]  (I think)
The h option means display those columns of data in hex.  I'm not sure
if I have the syntax exactly right, but it's close.
