If memory serves me right, the latest versions no longer need text
layers to be anchored.  They will be stored as separate layers, so
that the text can be re-edited.  Normally, this serves most purposes,
except for what you're about to do...

 After having created the text layer (and anchored it?), I want to do a
 color inversion. First I select the layer in the Layers Dialog (don't
snip
 If instead I use the menu and do Layer,Colors,Invert, the black text
 turns the color of its background (white) and so disappears because
 the area around the text does not turn black. I should be getting
 white text on a black ground.

Said filter works only on the selected layer (text).  Select the
background layer and repeat, to invert that, too.  This way, you have
the option of inverting only a certain part of a picture.

Your tutorial is outdated, and doesn't accommodate for new features
introduced in the 2.x series.  [That said, I think I was using the
anchor method of adding text but a year ago for a grade school
project, and when I came back in the fall and reinstalled The GIMP,
text had been implemented as seprate editable layers.  Also, moving,
resizing, scaling, skewing, or otherwise editing a text layer turns it
into a graphic layer.]

If you really want to anchor the layer, make sure that the text and
background layers are the only visible ones (if they're the only ones
you're working with, this is irrelivant, but in more advanced editing
this becomes important), then right click the image, search around in
the menus and click Merge Visible Layers.

If you _really_ want to lose all the transparency data, and make e.g.
inversion of the whole image easy, then you can simply flatten the
image -- but you'll lose any invisible layers and you won't e.g. be
able to move around various components.

Also, for your tutorial:  It may be easier to invert your background,
then change your foreground/pen color into the inverted of what you
would have chosen above, and then create text that is already
inverted.  Works for anything that you know how to find the inverted
colour of (e.g. white for black, and vice versa).

It may be worth reading the Changelog between 1.x and 2.x series,
and/or the 2.x documentation.  1.x documentation needs to have the
instructions converted into 2.x instructions on-the-fly, so if
you're good at fumbling around and figuring that kind of thing out
with something new, then you can try looking at the 1.x docs also.

Good luck learning how to use the Gimp!  IIRC, they say it's easier to
ask then to spend days fumbling around.  If you can fumble around in
seconds though... *shrugs*

it was written for gimp-1.0; i thas been ported a little forward but
still reflects gimp-1.2

 A secondary question is how to anchor it. When I do C-h, nothing
 changes. Is anchoring necessary in a simple project like this, and how
 do I know one layer is anchored upon another. One text seems to iply
 that in the Layers Dialog, to the right of the eye icon, the button
 acquires an anchor symbol. If I click tha button, I get a link
 symbol. I mention this only because it may be relevant to my primary
 question. 
 
i am curious where you found the keystrokes for this?

perhaps it would be good to stick to the menu entries and try to make
the layers shown match your layers.  meaning, if it is a layer of
blurred white text on a black background, look in the menues to see the
best way to make a layer that looks like that.

the text tool has changed and makes a different type of layer now.

can you find the key that merges a layer down?

 After having created the text layer (and anchored it?), I want to do a
 color inversion. First I select the layer in the Layers Dialog (don't
 know how to do it yet from keyboard), and with the image frame
 focused, I type C-i. All this does is to give the background a dotted
 outline and the text layer a mobile wavy outline.
 
again, you are asking questions using keystrokes.

since the tutorial was written using menu entries, it might be easier to
identify where you are at in those written words if you use the menu
entry and the words from the tutorial.

 If instead I use the menu and do Layer,Colors,Invert, the black text
 turns the color of its background (white) and so disappears because
 the area around the text does not turn black. I should be getting
 white text on a black ground.
 
the text tool has changed since the tutorial was ported to gimp-1.2.  if
you write to [EMAIL PROTECTED], you can get a long apology from him to
help you to understand as much as i do about the demise of the web team.

 Sorry for such an elementary question.
 
it would be easier if you asked a more elementary question.

i am curious where you found the need to translate the text into
keystrokes?
